But also elated? I take Lithium at 750mg. Hasn't done much for my depression but controlled the hypomania. I've been through a painfully depressive episode lately so I tried 20mg of prozac for a few days (Yes, I self medicate it and I have regrets). Now I know Prozac causes anxiety at first, but mine is beyond extreme. My heart is racing and I feel a looming hypomanic episode coming along. I feel happy but also very anxious. Should I stop taking it? I don't think I can take more of this anxiety. And does this amount of anxiety usually happen to BP people who take Prozac?
