TL;DR. Depressive disorders are conditions in which low mood or loss of interest persists for weeks and impairs daily life, alongside changes in sleep, appetite, energy, and concentration. They include major depression, persistent depressive disorder, and seasonal patterns, and they respond to antidepressants, therapy, or both.

Quick overview. Depressive disorders involve a persistent low mood or loss of interest that lasts at least two weeks and affects daily life. Care usually combines a psychiatric evaluation, medication when appropriate, coordinated therapy, and consistent follow up so you get fully better, not just slightly better.

Understanding depression

Depression is medical, and it's treatable

Depression is more than sadness. It's a shift in brain chemistry, energy, motivation, sleep, and thinking that can make ordinary tasks feel impossible. People often blame themselves, but depression is an illness, not a character flaw or a failure of effort.

Because depression has many faces, an accurate diagnosis matters. It can look like classic low mood, or it can show up as irritability, numbness, fatigue, or physical aches. It also overlaps with anxiety and can follow seasonal patterns. A careful evaluation finds the right diagnosis and the right plan.

Treatment

How we treat depression

Comprehensive evaluation

We assess your mood, sleep, energy, appetite, focus, and safety, and rule out medical contributors like thyroid issues or vitamin deficiency.

Medication when it helps

Non controlled antidepressants such as SSRIs, SNRIs, or bupropion can help when appropriate, chosen to fit your symptoms and side effect profile. For adults under 25, antidepressants carry an FDA warning about a short term increase in suicidal thoughts early in treatment, which is exactly why we schedule close follow up in the first weeks and watch for it together.

Therapy coordination

We coordinate evidence based therapy such as CBT or behavioral activation, which pairs well with medication or stands on its own.

Ongoing follow up

We track your response, adjust as needed, and aim for full remission, not partial improvement.

Beyond mood

What depression does to the whole system

Depression isn't only sadness. It slows thinking and concentration, disturbs sleep in both directions, flattens appetite or drives it up, drains energy, and strips interest from things that used to matter, a symptom called anhedonia that patients often find hardest to explain.

It also distorts self perception, generating guilt and hopeless conclusions that feel like facts. Recognizing these as symptoms, not truths, is often the first relief treatment brings.

Treatment

Matched to severity, measured over time

For mild depression, structured therapy alone is often enough. For moderate to severe depression, the combination of an antidepressant and therapy clearly outperforms either alone. We track your PHQ-9 score at each visit, so improvement is visible on paper, not just by impression.

Once you're well, the work shifts to staying well. Continuing treatment for the recommended months after recovery, protecting sleep, and keeping follow ups dramatically lowers the chance of relapse.

Frequently asked questions

Good questions, clear answers

Is depression really a medical condition?

Yes. Depression involves measurable changes in brain chemistry, sleep, energy, and thinking. It's a treatable illness, not a personal failing or something to push through alone.

Do you prescribe controlled medication for depression?

No. We treat depression with non controlled antidepressants such as SSRIs, SNRIs, or bupropion, paired with therapy when helpful.

How fast can I be seen?

Many people schedule a full evaluation as soon as availability allows. Depression responds best when care starts before symptoms deepen.

Is online care effective for depression?

Yes. Research shows telepsychiatry matches in person care for depression, and it removes the effort and travel that depression makes harder.

What's the difference between sadness and clinical depression?

Sadness is a normal emotion that passes. Clinical depression lasts two weeks or more, affects sleep, energy, appetite, and concentration, and drains interest from things you usually enjoy. The difference is persistence and impairment.

Can depression come back after treatment?

It can. Risk of recurrence drops sharply when treatment continues for the recommended time after you feel better, and when follow up stays consistent. We plan for prevention, not just recovery.

What happens if depression goes untreated?

Untreated depression tends to deepen, last longer with each episode, and raise risk to work, relationships, physical health, and safety. Earlier treatment is easier and more effective treatment.

Does online treatment work for depression?

Yes. Evaluations, medication management, and therapy delivered by video show outcomes comparable to office based care for depression, with fewer missed appointments.
