I also didn't believe a therapist could help.
My pdoc hospitalised me when he firsted dx'd me to get my meds sorted, do some blood tests and whatever. He MADE me see a T, who came to the hospital. I went to see her a few times after I left the hospital, but felt it didn't help much.

Then I started to get REALLY depressed. Landed back in hospital and my T was there again. After a few weeks I stopped therapy. Ultimately, she was probably just not right for me. I joined a few local forums and mailing lists and got a recommendation. I went to a T, and stayed with her for over a year, until I felt I was OK to stop therapy.

So, yet another non-believer has been converted, lol
