Sorry to hear your suffer from primarily depressions. I have bipolar disorder and have been in a horrible depression since last August. Medication and therapy don't seem to be helping in the least. Good for you for hanging in there and looking for solutions! I think many pdocs are hesitant to prescribe antidepressants for bipolar folks at the risk of triggering mania. For me, the only time an antidepressant has triggered mania was when I foolishly went off my mood stabilizer at the same time.

I'm not clear on whether any of the medications you listed is an antidepressant. If not, you may want to discuss the possibility of going on one with your pdoc. Best of luck!
