Depression is often treated as simply a chemical or behavioural problem to correct. Sometimes medication genuinely helps, and this work isn't opposed to that — but psychoanalytic therapy also asks a different question: what has your mind stopped letting you feel, and why?
Low mood can be a kind of shutting-down — a response to loss, disappointment, or a life that stopped matching what you needed from it. Rather than only pushing to "feel better" quickly, we slow down enough to understand what the depression is responding to.
This is steady, unhurried work — not because change should take longer than necessary, but because understanding what's actually going on tends to hold up better than symptom relief alone.
