Hi Mrs. Hyde,
Welcome and hello
BPD is a tough way to go through life, and it's not uncommon to use alcohol and other substances to self-soothe. Unfortunately, the solution is a problem all its own.
40 times in the hospital is a lot to go through. Is there a pattern to these hospitalizations? Meaning, is he drug seeking, or suicidal? Or does he end up there after drinking to excess?
How do you take care of yourself when he's in a dysregulation or drinking? To try and keep it from friends and family must be taking a big toll. Glad you reached out for support with people who understand what it's like.
