Clinical Depression: Recognizing It and What Actually Helps
Everyone has hard days. Major depressive disorder is different — a persistent change in mood and functioning that lasts most of the day, nearly every day, for at least two weeks, and doesn't resolve just because circumstances improve. It's genuinely common (roughly 1 in 5 women will experience it in their lifetime) and genuinely treatable, but recognizing it for what it is tends to be the slowest part.

What distinguishes it from a difficult stretch
Core symptoms include a persistently low or empty mood, loss of interest or pleasure in things you used to enjoy (anhedonia), changes in sleep or appetite in either direction, fatigue, trouble concentrating, feelings of worthlessness or excessive guilt, and thoughts of death or suicide. Meeting criteria generally means several of these, most of the day, nearly every day, for two weeks or more — a bad week after a hard event is different from this pattern, though it's worth taking seriously either way.
How this differs from PMDD
The key difference is timing. Depression is present more or less continuously, regardless of where you are in your cycle — it doesn't reliably lift for two symptom-free weeks after your period the way PMDD does. That said, an existing depression can genuinely worsen premenstrually (called premenstrual exacerbation) — a real and different pattern from PMDD itself, but one that still benefits from being named correctly, since it changes what treatment approach makes sense.
Perinatal and postpartum depression
Depression during pregnancy or in the year after delivery is common — roughly 1 in 8 people — and is not the same as the brief "baby blues" that resolve within two weeks. It's under-recognized in part because exhaustion and mood changes are expected after having a baby, which makes it easy to miss the line between adjustment and a treatable condition. This deserves the same evaluation and treatment as depression at any other time.
Treatment
Therapy (particularly cognitive behavioral therapy) and antidepressant medication (SSRIs and SNRIs are typically first-line) both work, and the combination often works better than either alone for moderate-to-severe depression. It typically takes 4-6 weeks to feel the full effect of a new antidepressant, which is worth knowing going in so an early lack of change doesn't read as the medication failing.
When it's an emergency
Thoughts of harming yourself, or thoughts that you'd be better off dead, are always an emergency — not something to mention only if it comes up. Call or text 988 (the Suicide & Crisis Lifeline), available 24/7, or go to an emergency room.
