I sort of have a theory and am curious what u all think. I was treated for depression since the age of 23 (altho it started at 16) and in my 30's i was diagnosed with Bipolar Disorder and what I am actually wondering if being on antidepressants for so long CAUSED the mania I was experiencing, what if they lift ur mood so high that u become manic as a result OF THE MEDICATION? Just food for thought, would love to hear back from u. Hugs.
