Dear Thea
Been there, done it. Your doctor was an idiot. Sorry. In your situation anybody I know would try to find a solution. You found the meds, I found hypnosis helping me better and cured me permanently. I used a special method called SRP - Subliminal Rationality Programming and it was great. I listen to a tape and fall asleep waking up feeling good.
Dont give doctors that power over you! It is no good, that you run around with guilt feelings on top of having your problems. Go and find a doctor who understands and maybe one day you will find someone who can help you permanently.
good luck'
Franz
