It certainly did for me. Practically the first thing my therapist said to me was exactly what he said to someone else before, since apparently it really helped the first person.

The next session was my last, when I told him I had figured out the issue. I don't even know what he said any more, but I haven't had that particular kind of depression recur for like 6 years now.

Gives no guarantees for your own experience of course, just wanted to give a different perspective.
