In short, I am a very well-managed case of BPD. I’ve been in therapy for years, on meds, and I have lots of insight. My sister, however, is a train wreck with her BPD. She is ruining her relationships with family members by accusing them of things, acting irrationally, spreading lies/exaggerations, refusing help, and wallowing in self-pity. It’s been a long time since I was my most severe, but I was never as severe as her. For those of you who have experienced severe BPD, especially in the form of wrecking familial relationships, what helped you get control of yourself? I don’t know what to do to help her. At this point, she will either die by s——-e or be kicked out of the family.
