I was originally Dx with MDD and PTSD, then they gave me ADs and I jumped into full blown mania w/ psychosis, and it got changed to BpI w/ PTSD. But I remained on ADs for years and was stuck in the revolving door or hospitals. I got wise said no more ADs but I also chucked out all the rest of the meds. Had some bad depressions but refused to see a Pdoc for any reason. Then a few year s ago things started get bad again and my T talked me into seeing a Pdoc, told them no ADs and they agreed, but gave me trazadone for sleep. Two weeks later I was in the hospital.
I've been struggling lately and finely saw a dr, said it was BP II and I'm on lamictal and latuda. So far it's great.

There is a site by a Dr Phelps, Psycheducation. Who explains really well about the BP spectrum continuum and everything that is between unipolar and BP I. It's well worth a read.
