My dx as BPII was a long time coming. I'd been dx'd with MDD for many years, which was also called treatment resistant. in time, I'd shown episodes which could not be attributed to MDD, to PTSD , etc. These were mixed episodes. I was then givn extensive testing and an interview about my earlier life. i was clearly hypo manic at various times in my life. My latest pdoc has treated me as though I was/am BPII. I am much more balanced and comfortable with Lamictal, etc
