It's totally possible to have both BP and BPD. I can only imagine how much that would suck. My friend has pretty severe BPD. I've seen how it can mess people up. If you fear it BPD, please talk to your doctor about it. My borderline friend utterly refused to pursue treatment for it for the longest time (even though I offered to drive her) and it only got worse. Two 51/50s in three years. (On a "lighter" note - I have a twisted sense of humor, sorry - imagine how much "fun" our other friends had having to deal with a coke-head borderline an a drunk manic-depressive! Ah, the "good ol' days." - which were obviously not so good.)

Hope whatever it is runs its course sooner rather than later!
