I am not a pdoc but it certainly sounds like BPD behavour. Have you looked at the criteria for being diagnosed with BPD? When I was being diagnosed I did a little bit of reading and it was like I was reading my life history, everything just fit. I found the most helpful book to be "BPD for Dummies", at the time I was reading it I could not focus on anything too technical but the for dummies book really broke things down for me.
