I can't believe a psychiatrist who doesn't adjust medication according to need. My doc changed my meds for two years before he found the right mix. Maybe you should see another dr. Take heart that you improved and overcame with the right medicine before. There's no reason why that can't happen again. I've survived for 50 years on medicine---can't do without it. with it, life can even be good.
I wish you all the good fortune and please keep posting. it will help you.
