One thing to think about is that different ssri antidepressants work differently from one person to the other (in my experience). I am on Cymbalta 120mg for depression, anxiety, big time OCD and actually joint pain associated with Lyme disease. It works great for me. I wouldn't even consider going off.
My wife has tried 3 or 4 different ssri's and has had her best luck with Cymbalta also, worst luck with Zoloft.
Anyway good luck, finding the right therapist/psychologist is tough.
