Hey YYZ,
I would think a bit more information is needed. Of course no one here can diagnose you, you would have to see a professional for that.
However, do you relate to the BPD traits in the DSM? Which ones? how many?

I have been told by others that I have signs of ADHD, however I've always thought that it was generational (high-stim society and tendency toward instant gratification via the internet and other technologies). I've also noticed that my mind jumps around a lot and I have a hard time concentrating and focusing sometimes, but nothing that impairs functioning. I do believe that those with BPD have structural and neurological brain differences than those without. We perceive, process and store things differently...our cognition is vastly different, IMO. We also seem to have a trend of memory impairment...
That's all I can really offer. Best wishes.
