I've read your posts, and from that limited information, I do not get the BPD vibe from you at all. I think that when drugs are involved in any situation BPD symptoms come out, especially when you have a pre existing BP diagnosis. Also, you are smart and probably overly introspective, so that might be part of the problem/thing that makes you interesting.
Like I said, I don't know you personally, but I have worked with many BPD individuals (I'm an LMSW), and I just don't see it.
