Medication, especially antidepressants, can kick up mania. I've had it happen to me. medications are really a dilemma...I would NOT be alive without medications. Having said that, it was a long road to the right medications and I had many reactions until I found the medications that both work and don't give me side effects. Prozac made me a zombie, Zoloft made me so manic I ended up in the phospital, and a few of the other antidepressants gave me hallucinations after I took them for a while. The other medications, all antidepressants, helped me hobble along (with good therapy), but when I hit the medication jackpot, my life changed to normal. I know no other way to explain it.
However...I do think the medications are causing a lot of the behaviors here. Whatever you decide to do, I wish you the best of luck. it takes a long time sometimes, but the end result is soooooo worth the long journey. (((Hugs)))
