Welcome SmFry,
I have a friend who has had similar experiences--tried different meds, gone to different doctors, and he's still struggling. Were you ever able to establish any continuity of care? Did you, for example, visit a psychiatrist every two months for a year or so? Did you stick with your meds?
In my case, I also went through several medications over a long,ten year period. Now, I think I've finally found a combination that works, but I always remain cautious.
I encourage you to work through the program and to use the community forums. Both help me come to terms with my "condition".
