I'm kinda in the same boat as you. I had been told I was BP and then my pdoc says personality disorder, sleep deprivation (which I don't have) and co-morbid depression.

I dunno what to think or if it matters. The medications I'm taking seem to be helping somewhat so I guess I'll just stick it out.

Hopefully you'll get treatment that works for you and in the end that's really all that matters.
