Quick Answer: What Is Depression?

Depression formally called Major Depressive Disorder (MDD) is a mood disorder characterized by persistent sadness, loss of interest in life, low energy, and a range of physical and cognitive symptoms that interfere with daily functioning. Depression is not the same as feeling sad. It is a clinical condition that changes how the brain regulates mood, motivation, sleep, and thinking. It is one of the most common and most treatable mental health conditions.

Depression vs. Sadness What Is the Difference?

Everyone feels sad sometimes. Grief, loss, disappointment, and hard seasons of life are a normal part of being human. Depression is different from ordinary sadness in several important ways:

Normal Sadness	Depression
Connected to a specific cause or event	May have no clear cause or persists beyond a cause
Improves with time or positive experiences	Does not lift with good news or positive events
Does not affect functioning for long	Significantly impairs work, relationships, or daily life
Person still experiences moments of joy	Loss of interest in most or all activities
Sadness fades as circumstances change	Lasts most of the day, nearly every day, for two weeks or more
Does not typically affect sleep or appetite	Almost always affects sleep, energy, and appetite

The defining feature of depression is not the intensity of sadness it is the persistence, the pervasiveness, and the loss of function. Many people with depression do not even describe feeling “sad” they describe feeling empty, numb, or like nothing matters anymore.

Signs and Symptoms of Depression

Depression affects how you think, how your body feels, and how you function. The DSM-5 requires five or more of the following symptoms to be present most of the day, nearly every day, for at least two weeks:

Emotional & Cognitive Symptoms	Physical & Behavioral Symptoms
Persistent sadness, emptiness, or hopelessness	Fatigue and loss of energy nearly every day
Loss of interest or pleasure in activities you used to enjoy	Changes in sleep insomnia or sleeping too much
Feelings of worthlessness or excessive guilt	Changes in appetite or weight
Difficulty concentrating, remembering, or making decisions	Moving or speaking more slowly than usual
Thoughts of death or suicide	Physical pain headaches, stomach problems with no clear cause
Feeling like a burden to others	Withdrawing from friends, family, and activities

Depression in Children and Teenagers

Depression in young people does not always look like adult depression. Children and teens may show depression through:

Irritability, anger, or frustration rather than sadness
Declining grades or school refusal
Social withdrawal dropping friends and activities
Physical complaints stomachaches or headaches with no medical cause
Increased sensitivity to rejection or criticism
Loss of energy and motivation that looks like "laziness" to others

Depression in teenagers is often missed because it does not look like adult depression. A teen who seems angry, irritable, or withdrawn rather than sad may be dealing with significant depression. The emotional experience is the same the external presentation is different.

Types of Depression

Major Depressive Disorder (MDD)

MDD is the most common form of depression. It involves episodes of depression lasting at least two weeks often much longer without treatment. Some people have a single episode in their lifetime. Others have recurrent episodes that come and go over years.

Persistent Depressive Disorder (Dysthymia)

Persistent depressive disorder involves a lower-grade depression that lasts for at least two years. It is less severe than major depression in any given moment but its persistence takes a toll. Many people with dysthymia feel like being depressed is just "who they are" and never seek help. It is very treatable.

Depression With Anxiety

Depression and anxiety co-occur so often that they are sometimes described as two sides of the same coin. About 50 percent of people with depression also have a significant anxiety disorder. When both are present, treating them together produces better outcomes than addressing only one. We specialize in both see our OCD and Anxiety Disorders pages for more.

Depression With OCD

Depression is extremely common in people with OCD often as a secondary condition that develops from years of living with intrusive thoughts and compulsions. When depression and OCD co-occur, we treat both as part of the same integrated plan.

Postpartum Depression

Postpartum depression is a serious but very common condition that develops after childbirth affecting approximately 1 in 7 new mothers. It is different from the "baby blues" (which resolve within a couple of weeks) and requires treatment. See our Postpartum Anxiety page for more on perinatal mental health conditions we treat.

Seasonal Affective Disorder (SAD)

Seasonal Affective Disorder is a pattern of depression that follows the seasons most commonly starting in fall or winter and lifting in spring. It is thought to be related to reduced sunlight exposure affecting serotonin and melatonin. SAD is treatable with therapy, light therapy, and medication.

What Causes Depression?

Depression is not caused by one single thing. It develops from a combination of biological, psychological, and life factors:

Brain chemistry. Depression involves changes in how the brain regulates neurotransmitters particularly serotonin, dopamine, and norepinephrine. These are real neurological differences, not imagined ones.
Genetics. Depression runs in families. Having a first-degree relative with depression increases your risk but it does not make depression inevitable.
Life events. Loss, trauma, relationship problems, financial stress, and major life transitions can trigger depression particularly in people who are already biologically vulnerable.
Chronic illness and pain. Living with ongoing physical health problems significantly increases depression risk.
Negative thinking patterns. Depression is maintained by specific ways of thinking about yourself, the world, and the future that CBT is specifically designed to address.

Depression is not caused by weakness, laziness, or not trying hard enough. It is a condition with real biological roots and one that is significantly worsened by the stigma that tells people they should be able to fix it on their own.

How Is Depression Treated?

Depression is one of the most treatable mental health conditions. With the right approach, most people see significant and lasting improvement. At Anxiety & OCD Treatment Specialists, we use evidence-based therapy and we treat depression in the context of the whole person, including any anxiety, OCD, or trauma that is contributing to it.

Cognitive Behavioral Therapy (CBT)

CBT is the most researched and most effective psychotherapy for depression. It works by identifying the specific patterns of thinking that maintain depression and helping you develop more accurate, balanced ways of responding to them.

In depression, CBT targets three interconnected problems:

Negative thoughts about yourself: "I am worthless." "I am a burden." "Nothing will ever change."
Negative thoughts about the world: "Everything is hard." "No one cares." "There is no point."
Negative thoughts about the future: "Things will never get better." "I will always feel this way." "There is nothing to look forward to."

These three patterns sometimes called the cognitive triad are the engine of depression. CBT dismantles them directly and builds skills that produce lasting change.

Behavioral Activation

One of the most powerful parts of CBT for depression is behavioral activation deliberately re-engaging with activities and experiences, even when motivation is low. Depression creates a withdrawal cycle: you feel bad, so you stop doing things, which makes you feel worse, which makes you withdraw more. Behavioral activation breaks this cycle by acting first and waiting for motivation to follow rather than waiting to feel better before doing anything.

Addressing Underlying Conditions

At our practice, we treat depression in the context of the whole picture. When depression co-occurs with anxiety, OCD, PTSD, or other conditions which it very commonly does we address all of them as part of the same integrated plan. Treating only the depression while leaving the anxiety or OCD untreated rarely produces lasting results.

Medication

We are therapists, not psychiatrists, and do not prescribe medication. However, for moderate to severe depression, medication alongside therapy often produces significantly better outcomes than either alone. Antidepressants particularly SSRIs and SNRIs are safe and effective for most people. We can refer you to a trusted psychiatrist and coordinate care when medication may be appropriate.

Depression and the Motivation Problem

One of the cruelest features of depression is that it removes the motivation to get help. Everything feels pointless including therapy. Making the phone call, scheduling the appointment, showing up for the first session all of this can feel impossible when you are in the depths of depression.

This is not weakness. It is a symptom of the illness itself.

We understand this. Our first appointment is low-pressure and focused on understanding where you are not on what you need to do. If the only thing you can do today is read this page, that is enough. When you are ready, we are here.

Virtual therapy is especially well-suited for depression because depression itself makes leaving the house harder. Being able to attend sessions from home removes one of the biggest barriers to getting consistent care.

Frequently Asked Questions

Is depression the same as feeling sad?

No. Sadness is a normal human emotion that comes and goes in response to life events. Depression is a clinical condition that persists regardless of circumstances, affects nearly every area of daily functioning, and does not lift with ordinary positive experiences. Many people with depression do not even feel sad they feel numb, empty, or disconnected. If symptoms have lasted more than two weeks and are affecting your work, relationships, or daily life, it is worth talking to a specialist.

Can depression go away on its own?

Mild depressive episodes sometimes resolve on their own over time. But moderate to severe depression rarely does and the longer it goes untreated, the harder it becomes to treat and the more damage it does to relationships, careers, and quality of life. Depression also has a tendency to recur. Treatment not only helps you feel better now it gives you skills that reduce the risk of future episodes.

I have been depressed for years. Is it too late to get help?

It is never too late. Long-standing depression including persistent depressive disorder that has been present for years responds to CBT and medication in the same way as shorter episodes. Many people who have lived with depression for most of their lives describe therapy as the first time they have felt truly like themselves. The length of time you have been struggling does not predict your outcome. Treatment does.

How is depression different from burnout?

Burnout is a state of exhaustion from chronic stress particularly work-related and it shares several features with depression: fatigue, reduced motivation, and a sense of emptiness. The key difference is that burnout typically improves significantly with rest, reduced stress, and changed circumstances. Depression does not. If you have taken time off, reduced stress, and still do not feel like yourself, depression is worth evaluating. The two can also co-exist.

Can depression be caused by anxiety?

Yes this is extremely common. Anxiety and depression co-occur in about 50 percent of cases. Living with chronic anxiety is exhausting and demoralizing, and over time it often develops into depression. When both are present, treating only the depression without addressing the anxiety leaves a major driver of the problem unresolved. We treat both conditions together as a standard part of our approach.

Do I need medication to treat depression?

Not necessarily. CBT alone is highly effective for mild to moderate depression and produces results that tend to last longer than medication alone because it addresses the thinking patterns that drive depression, not just the symptoms. For moderate to severe depression, the research suggests that medication alongside therapy produces the best outcomes. We will discuss what makes sense for your specific situation at your first appointment.

Depression Is Not Your Fault and It Is Not Permanent.

Depression lies to you. It tells you nothing will help, that you do not deserve to feel better, that this is just who you are. None of that is true. Depression is a treatable condition, and most people who get the right help feel significantly better and stay better.
