Depression is not sadness, and it is not a failure of effort. It is a medical condition that changes how the brain regulates mood, sleep, appetite, energy, and the ability to feel interest in anything. It is also one of the most treatable conditions in medicine — which is worth saying out loud, because depression itself tells people the opposite.
Golden Coast Rehab treats major depressive disorder, persistent depressive disorder, and depressive episodes within other conditions, for adults across San Diego County. Treatment happens during the day or evening, and you sleep at home.
Some people come to us after months of trying to push through alone. Some come after a hospital stay. Some come because someone who loves them made the call. All of those are legitimate ways to start.
Programs available for depression
Golden Coast Rehab is a contracted provider of Specialty Mental Health Services (Partial Hospitalization Program and Intensive Outpatient Program) for the County of San Diego, Behavioral Health Services, under County Contract 575462. Both programs serve adults 18 and older whose primary condition is a mental health condition, and both are delivered at our La Mesa facility.
Partial Hospitalization Program (PHP)
Day treatment for depression is for people whose symptoms are severe enough that ordinary life has stopped functioning — not getting out of bed, not eating, not able to work, or recovering from a psychiatric hospitalization. PHP runs during the day, several days a week, and you go home each evening. It is the most structured level of care we offer.
Intensive Outpatient Program (IOP)
IOP suits depression that is real and disabling but not stopping you from holding a schedule together. IOP is several sessions a week rather than full days, so it fits around work, school, and family. Many people step down into IOP from PHP; others start here.
We do not provide residential or inpatient treatment. If your assessment shows you need a higher level of care than we offer, we will tell you plainly and help you find it.
What treatment looks like
Nobody walks in knowing how this works. Here is the actual sequence for depression treatment here, start to finish.
Intake and assessment
A clinician spends time with you on your symptom history, sleep, appetite, medical history, medications, substance use, and safety — including direct questions about thoughts of suicide. Those questions are asked of everyone. Answering honestly does not automatically mean hospitalization; it means we plan care that accounts for the truth.
The first two weeks
The first goal is stabilization and structure. You will start individual therapy and daily or near-daily groups, and if medication is part of the plan, meet with our Medical Director, Dr. Sanjai Mathew Thankachen, MD, a board-certified psychiatrist. Antidepressants usually take several weeks to show full effect, so early gains often come from routine, activity scheduling, and sleep before they come from medication.
Active treatment
Individual and group therapy built on cognitive behavioral therapy and behavioral activation, plus skills work on sleep, rumination, and self-criticism. If medication was started, doses are adjusted based on your response. Treatment planning is reviewed with you, not decided about you.
How progress is measured
Depression symptoms are tracked with the PHQ-9, a nine-item questionnaire covering mood, interest, sleep, appetite, energy, concentration, and thoughts of self-harm. You complete it at intake and repeat it during treatment, so improvement is measured rather than assumed — and so a plan that is not working gets changed on evidence instead of on impression. Where anxiety is also in the picture, the GAD-7 is used alongside it. Your scores are reviewed with you, read next to what you and your clinician are seeing week to week.
Stepping down and aftercare
As symptoms lift, care steps down — PHP to IOP, IOP to weekly outpatient therapy — with a written plan that names your warning signs, your medications, your outpatient providers, and who to call. Recovery from depression is rarely a straight line, and the plan assumes that. Typical length of stay is around six weeks in PHP and around six weeks in IOP, but length is a clinical decision made by your treatment team based on how you are actually doing, not a fixed schedule.

Common Signs of Depression
Depression looks different from the outside than it feels from the inside. These are the patterns that most often bring people, or their families, to call.
01.highThoughts of suicide or of not wanting to be here
Thoughts range from passive (wishing you would not wake up) to active planning. They are a symptom of the illness, not a character flaw, and they are treatable.
Health Risks: Any thought of suicide warrants same-day help. Call 988 or the Access and Crisis Line at 1-888-724-7240.
02.highWithdrawal from everyone and everything
Canceling plans, ignoring calls, and pulling back from people who care. Depression makes isolation feel like relief while it deepens the illness.
Health Risks: Isolation removes the exact supports that protect against worsening symptoms.
03.moderateLoss of interest in things that used to matter
Called anhedonia — hobbies, food, sex, and relationships all go flat. This is often the symptom people notice before they notice sadness.
Health Risks: Frequently mistaken for laziness or burnout, which delays treatment for months.
04.moderateSleep and appetite that have gone wrong
Sleeping far too much or waking at 3am and not getting back down; eating almost nothing or eating constantly. Weight often shifts noticeably.
Health Risks: Disrupted sleep worsens mood directly, creating a loop that is hard to break without intervention.
05.moderateExhaustion and slowed thinking
Ordinary tasks feel physically heavy. Concentration, decisions, and memory get worse, which people often fear means something neurological.
Health Risks: Cognitive symptoms put jobs and school at risk and are a common trigger for giving up on treatment.
Support for families
Watching someone you love disappear into depression is exhausting and lonely, and advice like 'just get out more' rarely helps either of you. Families do best when they understand that low energy and irritability are symptoms rather than choices, and when they have somewhere to put their own worry.
With your consent, family members can be included in treatment planning and family sessions. Without your consent, they cannot — your privacy is protected by law, and we will explain to your family what we can and cannot share. More for the people who love you: For Families.
Coverage and cost
If you have Medi-Cal in San Diego County — any of the four managed care plans — treatment here can be covered at no cost to you, because specialty mental health services are administered by San Diego County Behavioral Health Services rather than by your plan. Full detail on how Medi-Cal works here.
Call (858) 925-8589 to check your eligibility. Our line is answered 24 hours a day. If you are in crisis, the San Diego County Access and Crisis Line is available around the clock at 1-888-724-7240.
