Feeling overwhelmed, exhausted, worried, unmotivated, or unable to concentrate can make it difficult to understand what is actually happening with your mental health.
Is it anxiety?
Is it depression?
Could it be both?
Depression and anxiety are different mental health conditions, but they can share several symptoms. Both can affect sleep, concentration, energy, relationships, work, and everyday functioning. Anxiety can leave someone feeling constantly tense or worried, while depression can make everyday activities feel difficult or meaningless. When symptoms overlap, however, the distinction is not always obvious.
It is also possible to experience anxiety and depression at the same time.
Understanding the differences can help you recognize when symptoms deserve professional attention, but an online symptom list cannot determine a diagnosis. A psychiatric evaluation considers the pattern, duration, severity, history, and impact of symptoms as well as other possible explanations.
Here is what to know about depression vs. anxiety, including common symptoms, important differences, how the conditions can overlap, and when it may be time to talk with a mental health professional.
A simplified way to understand the difference is that anxiety often involves excessive fear, worry, apprehension, or anticipation of potential threats, while depression commonly involves persistent low mood or loss of interest or pleasure.
The distinction is more complicated in real life.
Someone with anxiety may also feel exhausted, discouraged, or irritable. Someone with depression may worry about work, relationships, finances, health, or the future.
This is why clinicians do not diagnose these conditions based on one symptom.
They look at the overall pattern.
With anxiety, thoughts may frequently revolve around questions such as:
What if something goes wrong?
What if I make a mistake?
What if something bad happens?
With depression, thoughts may be more likely to involve themes such as hopelessness, loss, worthlessness, or diminished expectations about the future.
These are general patterns rather than diagnostic rules.
Anxiety itself is a normal human emotion.
Feeling anxious before an important presentation, medical procedure, major decision, or unfamiliar situation does not automatically mean someone has an anxiety disorder.
Anxiety becomes a mental health concern when symptoms are excessive, persistent, difficult to control, or significantly interfere with everyday life.
There are also different types of anxiety disorders. Symptoms therefore vary depending on the individual and diagnosis.
Someone with anxiety may experience psychological symptoms, physical symptoms, or both.
Possible anxiety symptoms can include:
Not everyone with anxiety experiences every symptom.
The nature of the fear or worry also matters when determining whether symptoms fit a particular anxiety disorder.
Depression involves more than having a bad day or temporarily feeling sad.
Depressive disorders can affect mood, motivation, thinking, sleep, appetite, energy, interest, relationships, and overall functioning.
A person experiencing depression may find that activities they previously enjoyed no longer feel rewarding. Getting out of bed, completing work, responding to messages, exercising, cooking, or maintaining relationships may begin to feel unusually difficult.
Depression can range considerably in severity.
Some people continue meeting many responsibilities while experiencing substantial internal distress. Others experience symptoms severe enough to significantly disrupt everyday functioning.
Depression symptoms may include:
Again, a diagnosis cannot be made from a checklist alone.
Clinicians consider the combination of symptoms, how long they have been present, their severity, their effect on functioning, and whether another condition better explains them.
One reason people struggle to distinguish anxiety vs. depression is that several symptoms can occur with either condition.
Common areas of overlap include concentration problems, sleep disturbances, fatigue, irritability, changes in motivation, and difficulty functioning.
But the underlying reason for the symptom may differ.
For example, someone with anxiety might struggle to concentrate because their attention is repeatedly pulled toward worries.
Someone with depression might struggle to concentrate because thinking feels slowed, energy is low, and engagement with tasks has decreased.
The outward symptom may look similar while the internal experience is different.
Thought patterns can provide useful clues, although they cannot diagnose a condition.
Anxiety frequently involves anticipation.
A person may repeatedly imagine negative possibilities and have difficulty disengaging from them.
Thoughts might involve work performance, relationships, health, finances, family, safety, or everyday decisions.
The mind may repeatedly ask:
“What if?”
Even when someone recognizes that a worry may be excessive, stopping the cycle can be difficult.
Depression can involve a different pattern.
Thoughts may center around hopelessness, low self-worth, guilt, failure, or a belief that circumstances will not improve.
Rather than fearing what might happen, someone may feel that improvement is unlikely or that activities are no longer worth pursuing.
These patterns can also coexist.
Someone can feel hopeless about the future while simultaneously worrying intensely about it.
Both conditions can interfere with sleep.
With anxiety, a person may lie awake because their mind feels active. They may replay conversations, anticipate problems, plan repeatedly, or worry about what needs to happen tomorrow.
Depression can also cause difficulty sleeping, but it may present differently.
Some people wake earlier than intended. Others have fragmented sleep or sleep for long periods while still feeling tired.
Because sleep disturbances occur in many psychiatric and medical conditions, sleep patterns alone cannot distinguish anxiety from depression.
However, describing exactly how your sleep has changed can provide useful information during a psychiatric evaluation.
Fatigue is another symptom that can occur with both.
Anxiety can be exhausting.
Persistent worry, physical tension, disrupted sleep, and a constant sense of being on alert can leave someone mentally and physically drained.
Depression can also cause substantial loss of energy.
Everyday activities may require more effort than usual, and motivation may become difficult to access.
When discussing fatigue with a clinician, it is helpful to describe when it started, whether sleep is restorative, whether you have lost interest in activities, and whether worry is consuming significant mental energy.
Medical causes of fatigue may also need consideration.
Difficulty concentrating is common in both conditions.
With anxiety, concentration may be interrupted by worry.
You may read the same paragraph repeatedly because your thoughts keep returning to something that might go wrong.
During a conversation, you may realize you were mentally rehearsing tomorrow's meeting rather than listening.
With depression, concentration problems may be associated with reduced energy, slowed thinking, low motivation, or difficulty engaging with the task.
People may describe their thinking as foggy or unusually slow.
Concentration problems can also occur with ADHD, sleep deprivation, substance use, medication effects, stress, and medical conditions.
This is one reason concentration difficulty alone should not be used to self-diagnose anxiety, depression, or ADHD.
Reduced motivation is commonly associated with depression, but anxiety can interfere with action too.
Someone with depression may think:
“I don't have the energy.”
“I don't care about this anymore.”
“Nothing seems enjoyable.”
Someone with anxiety may want to complete the task but feel unable to begin because of fear, uncertainty, perfectionism, or excessive worry.
For example, a person may repeatedly postpone sending an email because they are afraid of saying the wrong thing.
Another person may leave the email unanswered because depression has made ordinary responsibilities feel overwhelming and unimportant.
The behavior looks similar.
The reasons behind it may be different.
Overthinking is not a diagnosis.
It can occur with anxiety, depression, ADHD, stress, and other conditions.
In anxiety, repetitive thinking often focuses on possible future threats or uncertainty.
A person might repeatedly consider every possible outcome of a decision.
In depression, repetitive thoughts may involve past mistakes, regrets, perceived failures, guilt, or negative beliefs about oneself.
Clinicians sometimes distinguish between worry and rumination, although people can experience both.
If repetitive thinking is interfering with sleep, concentration, relationships, or daily functioning, it is worth discussing during an evaluation.
It can be either.
Anxiety can leave someone feeling chronically tense and overstimulated. Small interruptions or frustrations may therefore feel unusually difficult to tolerate.
Depression can also involve irritability.
Not everyone experiencing depression primarily describes feeling sad. Some people notice that they have become more withdrawn, impatient, frustrated, or easily irritated.
This is another example of why one symptom cannot reliably distinguish the two conditions.
Restlessness is often associated with anxiety.
A person may feel unable to relax, constantly need to move, or experience an uncomfortable internal sense of tension.
However, some people experiencing depression can also have agitation or restlessness.
Medication effects and other psychiatric or medical conditions may also contribute.
Persistent or new restlessness should therefore be evaluated in context rather than automatically attributed to anxiety.
Loss of interest or pleasure is particularly important when evaluating depression.
Someone may stop enjoying hobbies, social activities, exercise, sex, food, entertainment, or time with other people.
They may continue participating because they know they are supposed to, but the experience feels emotionally flat.
Anxiety can also lead someone to stop activities, but avoidance may occur for a different reason.
They might still want to participate but avoid the activity because it causes fear or worry.
For example, someone with anxiety may want to attend a social event but avoid it because they are afraid of being judged.
Someone with depression may decline because socializing no longer feels enjoyable or they lack the energy to participate.
Again, the distinction depends on the underlying experience.
Anxiety and depression frequently occur together, but it is usually too simplistic to assume that one condition directly caused the other in every case.
Persistent anxiety can be exhausting and disruptive.
Someone who spends months struggling with worry, poor sleep, avoidance, relationship difficulties, or reduced functioning may also develop depressive symptoms.
Similarly, depression can create circumstances that increase anxiety.
Difficulty completing work, managing finances, maintaining relationships, or meeting responsibilities may create additional worry.
Rather than trying to determine which condition “caused” the other without an evaluation, it is often more useful to identify the symptoms currently present and how they interact.
Yes.
Depression and anxiety can occur together.
A person might experience persistent low mood, reduced interest, low energy, and hopelessness while also experiencing excessive worry, tension, restlessness, and difficulty controlling anxious thoughts.
When conditions overlap, treatment planning needs to account for the complete symptom picture.
Treating only one set of symptoms may leave important difficulties unaddressed.
A psychiatric evaluation can help clarify whether symptoms fit depression, an anxiety disorder, both, or another explanation.
There is no useful universal answer.
Both can range from relatively mild to severe and disabling.
One person's anxiety may interfere substantially with work, relationships, sleep, and basic functioning. Another person's depression may have a similarly serious impact.
Severity and impairment matter more than trying to determine which diagnosis is inherently worse.
If symptoms are affecting your ability to function or causing significant distress, they deserve attention regardless of the label.
Both depression and anxiety can affect women, and symptoms may overlap with other concerns such as ADHD, sleep difficulties, chronic stress, and medical conditions.
Women may sometimes interpret longstanding anxiety, disorganization, concentration difficulties, or emotional overwhelm as personal shortcomings rather than symptoms worth evaluating.
At the same time, concentration problems and overwhelm should not automatically be attributed to ADHD or anxiety.
Saltmeadow Psychiatry has separate resources addressing ADHD in women and ADHD vs. anxiety, which can be helpful when attention symptoms are part of the clinical picture.
A comprehensive evaluation is particularly useful when several possible explanations overlap.
Men can also experience both anxiety and depression, although the way someone describes distress varies considerably.
Some people may be more likely to report irritability, sleep problems, difficulty concentrating, reduced motivation, physical symptoms, or changes in alcohol or substance use rather than initially describing themselves as sad or anxious.
Symptoms should be evaluated based on the individual rather than assumptions about how a particular person is supposed to experience depression or anxiety.
Depression, anxiety, and ADHD can all affect concentration, motivation, organization, sleep, and everyday functioning.
However, ADHD is a neurodevelopmental condition with a different clinical history from depressive and anxiety disorders.
When evaluating possible adult ADHD, clinicians may ask whether attention, organization, impulsivity, or related difficulties were present earlier in life.
A person whose concentration problems appeared only after becoming significantly depressed or anxious may require a different diagnostic consideration from someone who describes longstanding difficulties dating back to childhood.
It is also possible to have ADHD alongside depression or anxiety.
This is why a careful history matters.
Burnout is another term frequently used when people feel emotionally and physically exhausted.
It is often associated with prolonged occupational or caregiving stress and may involve exhaustion, reduced effectiveness, detachment, or cynicism.
Some burnout symptoms overlap with depression.
However, burnout and depressive disorders are not interchangeable concepts.
If low mood, loss of interest, hopelessness, sleep problems, concentration difficulties, or other symptoms extend beyond a particular stressful context, a mental health evaluation may be appropriate.
Persistent symptoms should not automatically be dismissed as burnout.
Yes.
Some medical conditions can cause or contribute to symptoms that overlap with psychiatric disorders.
Fatigue, sleep changes, concentration difficulties, changes in appetite, restlessness, or mood changes can have multiple explanations.
Medications and substances may also affect mental health symptoms.
A psychiatric evaluation therefore includes relevant medical history and current medications.
Depending on the symptoms and circumstances, coordination with primary care or another medical professional may be appropriate.
There is no single blood test, brain scan, or online questionnaire that independently diagnoses every case of depression or anxiety.
Diagnosis is based largely on clinical evaluation.
A psychiatrist may ask about:
The clinician may also consider whether another condition could better explain the symptoms.
The purpose is not simply to count symptoms.
It is to understand the entire pattern.
A psychiatric evaluation is an opportunity to discuss what you are experiencing and how symptoms affect your life.
You do not need to arrive already knowing whether you have anxiety or depression.
In fact, determining that is part of the evaluation.
Your psychiatrist may ask when symptoms began, whether they are constant or episodic, what makes them better or worse, and whether you have experienced similar periods before.
Previous medication and therapy history may also be discussed.
If you have difficulty explaining your symptoms, consider writing down the most important changes before your appointment.
Saltmeadow Psychiatry has a separate guide explaining what to expect during a psychiatric evaluation for patients who want to prepare for their first visit.
Online screening tools may help identify symptoms worth discussing with a healthcare professional, but they do not replace a clinical evaluation.
A questionnaire cannot always determine why symptoms are occurring.
For example, answering that you frequently have trouble concentrating does not tell you whether the cause is anxiety, depression, ADHD, poor sleep, substance use, medication effects, a medical condition, or another factor.
Screening is different from diagnosis.
If symptoms are persistent or significantly affecting your life, professional evaluation provides a more complete assessment.
Treatment depends on the diagnosis, severity, individual circumstances, medical history, previous treatment, and patient preferences.
Approaches may include:
Some people benefit from psychotherapy alone.
Others may benefit from medication.
Some receive both.
Treatment should be individualized rather than based solely on what worked for another person.
Several categories of psychiatric medications may be used in the treatment of depressive or anxiety disorders.
Some antidepressants are used for both depression and certain anxiety disorders.
However, the fact that a medication can be used for both does not mean the conditions are identical.
Medication selection depends on the diagnosis, symptoms, treatment history, side effects, medical considerations, interactions, and individual circumstances.
A psychiatrist can discuss why a particular medication is being considered, expected benefits, possible side effects, and how treatment response will be monitored.
Not everyone experiences adequate improvement with the first antidepressant they try.
Some people have a partial response. Others experience side effects that limit treatment. Some may need the diagnosis or overall treatment strategy reconsidered.
If antidepressants are not working, do not abruptly discontinue medication or change the dose without discussing it with your prescriber.
Your psychiatrist may review how long the medication has been taken, dosage, adherence, symptoms, side effects, previous treatment, and whether another condition is contributing.
Saltmeadow Psychiatry has a dedicated resource on what to do when antidepressants are not working that explores this topic in greater detail.
Co-occurring symptoms can influence treatment planning.
If someone has significant anxiety as well as depression, a psychiatrist may consider the complete symptom pattern when selecting and monitoring treatment.
Some patients are particularly concerned about changes in sleep, restlessness, or anxiety when starting medication.
These concerns should be discussed rather than ignored.
Medication management provides an opportunity to monitor both intended benefits and unwanted effects over time.
Psychiatric medication management is the ongoing process of evaluating whether medication is appropriate, monitoring treatment response and side effects, and adjusting treatment when necessary.
It involves more than simply obtaining refills.
Follow-up visits may assess mood, anxiety, sleep, concentration, functioning, medication adherence, side effects, and other changes.
This can be especially valuable when depression and anxiety overlap because improvement in one symptom does not necessarily mean every concern has resolved.
Psychotherapy can play an important role in treating depression and anxiety.
The appropriate therapy approach depends on the diagnosis, individual needs, and treatment goals.
Therapy can help people better understand patterns involving thoughts, behaviors, avoidance, stress, relationships, and emotional responses.
Some patients work with a therapist while seeing a psychiatrist separately for medication management.
When appropriate and with permission, coordinated care can help different clinicians understand the overall treatment plan.
You do not have to wait until symptoms become unbearable before seeking an evaluation.
Consider professional help when anxiety, depression, or related symptoms are persistent, worsening, difficult to manage, or interfering with your life.
Examples include:
Early evaluation may help clarify what you are experiencing and what treatment options are appropriate.
If you are seeking help for possible depression and anxiety, useful questions can include:
Understanding the treatment plan can make it easier to participate actively in your care.
You do not need to prepare extensively, but a few notes can be helpful.
Consider writing down:
Try to describe how symptoms affect actual daily life.
For example, “I am anxious” is useful, but “I spend several hours worrying at night and sleep only a few hours” provides additional context.
Similarly, “I feel depressed” can be expanded by explaining that you have stopped seeing friends, lost interest in hobbies, or struggle to complete work.
Symptoms can fluctuate, and some periods of emotional distress may improve with time, changes in circumstances, support, or other factors.
However, persistent or severe symptoms should not simply be assumed to disappear on their own.
Untreated symptoms can continue affecting work, relationships, sleep, physical health behaviors, and overall quality of life.
The appropriate response depends on severity, duration, impairment, safety concerns, and individual circumstances.
An evaluation can help determine whether formal treatment is warranted.
Depression can involve thoughts about death, suicide, or self-harm.
Severe anxiety can also become overwhelming and may occur alongside significant safety concerns.
If you are in immediate danger or unable to keep yourself safe, do not wait for a routine outpatient psychiatric appointment.
In the United States, call or text 988 to reach the Suicide & Crisis Lifeline.
If there is an immediate emergency, call 911 or go to the nearest emergency department.
If you are trying to determine whether you are experiencing depression vs. anxiety, you do not have to figure it out from symptom lists alone.

Anxiety commonly involves excessive fear, worry, tension, or anticipation of potential threats. Depression commonly involves persistent low mood or reduced interest and pleasure, along with other emotional, cognitive, and physical symptoms. There is significant overlap, so diagnosis depends on the overall symptom pattern rather than one characteristic.
Consider whether your experience is dominated by persistent worry and fear, low mood and loss of interest, or a combination of both. However, self-assessment cannot reliably establish a diagnosis. A mental health professional can evaluate the duration, severity, pattern, and impact of your symptoms.
Yes. Anxiety and depression can occur together. Someone may experience excessive worry and tension while also having low mood, reduced interest, low energy, or hopelessness.
It can occur with both. Anxiety-related repetitive thinking often focuses on potential future problems, while depressive rumination may focus more on past events, perceived failures, guilt, or negative beliefs. These patterns are not diagnostic by themselves.
Either condition can contribute to fatigue. Anxiety can interfere with sleep and create prolonged physical and mental tension. Depression can cause low energy, sleep changes, and reduced motivation. Medical conditions can also cause fatigue, so persistent symptoms should be evaluated appropriately.
Concentration problems can occur with both. Anxiety may interfere with concentration because worry repeatedly captures attention, while depression may involve reduced energy, motivation, or slowed thinking. ADHD, sleep problems, medications, substance use, and medical conditions can also affect concentration.
The conditions frequently occur together, and prolonged anxiety may contribute to emotional distress that includes depressive symptoms. However, the relationship varies between individuals, and it is not always possible or useful to say that one condition directly caused the other.
Depression can coexist with anxiety, and difficulties associated with depression may create additional worries about work, relationships, health, or the future. A psychiatric evaluation can help determine the pattern of symptoms.
Neither condition is universally more severe than the other. Both can range from mild to severe and can significantly affect daily functioning. The important question is how much your symptoms are affecting your life and safety.
Certain antidepressants are used to treat depressive disorders as well as some anxiety disorders. The appropriate medication depends on diagnosis, symptoms, medical history, previous treatment, potential side effects, and other individual factors.
Treatment planning can account for both sets of symptoms. Depending on the individual, treatment may include psychotherapy, medication, or a combination of approaches. Your clinician may monitor whether both depressive and anxiety symptoms are improving.
Yes, some symptoms can overlap. Anxiety and ADHD can both contribute to concentration difficulties, restlessness, procrastination, and feeling overwhelmed. ADHD typically involves a broader developmental history, which is one reason a comprehensive evaluation is important.
Depression can cause difficulty concentrating, reduced motivation, forgetfulness, and difficulty completing tasks. These symptoms can resemble aspects of ADHD, but their history and context may differ. It is also possible for both conditions to occur together.
Consider an evaluation when symptoms are persistent, worsening, interfering with work or relationships, affecting sleep or daily functioning, or not improving with current treatment. You can also seek an evaluation when you simply are not sure what is causing your symptoms.
