Go for it. BPD is complex, as are the people diagnosed with it. Anything that sheds more understanding on the subject could be of great help. I have a relative who's diagnosed with BPD. I don't know if he really has it or not. He's had several other diagnoses, but borderline seems to be the one that sticks, largely because he self-injures and has trouble with emotional impulsiveness and mood swings. But otherwise ... I'm still wondering.

He fits the criteria superficially, for sure. As a family member I'd certainly welcome books, blogs and articles that gave some alternative views of the diagnosis.
