I have BPD but this title spoke out to me. Like someone else, I think all PD's tend to be isolating. I know for me I have a hard time getting attached to anyone and tell myself often I'd enjoy having more friends but when it comes down to it? I don't try. It's really on me.
As for not having many forums/info for you out there that must be tough. I know I use info available as a coping mechanism to know I am not alone and I cannot imagine what it is like not to have that. Just keep trying. *hugs*
