I still don't know. (No diagnosis.) The pdoc who treated me during my last hospitalization said she thought there might be a "bipolar element" to what's going on with me (whatever that means.) I've often thought there was a time, when I was younger, I might have been diagnosable as having BPD. But from the little bit of reading I've done I can see myself as possibly having BP II as well. As I understand it there are a lot of similarities between BPD & BP II.
