There is a percentage of those who haven’t (accidentally or intentionally) taken themselves out by the time they reach their 40s and 50s who do see a reduction in symptoms. My MIL actually had a period of several months, about a year prior to her death, where she was almost normal. Oddly, she was going through hypnosis to stop smoking at the time. It was the most peaceful the interactions with her had ever been, and my husband still remarks that he would like to think that person was who she was at the core of her being, and that the disease had simply buried that person for the majority of her life.
However, it is rare that MHPs see the tail-end of BPD; aged people tend to not want mental health assistance, so we don’t get them as much in the clinical setting, and the families have either gotten to a point of acceptance or avoidance. We usually see the full-blown cases, the ones in their 20s and 30s, and they are for the most part intractable and incurable. Also, with the current state of mental health care, we simply don’t see people for ten years. So you battle with the same shit for a year or two, or three, and throw your hands up and say screw it.
olives, I’m going to answer two of your questions. The first was directed toward me, and that’s if I allow patients to have tantrums in my office. When I had an office, I would allow certain things- yelling, cursing, punching pillows, etc- if it was therapeutic; if it was for the sake of yelling, etc., then no. But if it served a greater good- if the client was processing something by engaging in the behavior- then yes. If they needed to break something, I had things on hand that were acceptable. But I never, ever allowed them to just grab things and throw. At work now, we have several kids who I have no doubt will grow up to be BP, and they LOVE to break things. As long as they’re breaking their own stuff, I let them. They want to rip their rooms apart, destroy their radio and their gameboy and their toys? Go to it. When you calm down, you’re going to be pretty bummed out that you don’t have those things anymore. They try going after agency stuff- furniture, unit-owned radios or tvs, hallway displays, etc- they’re going to get restrained (or secluded).
Your second question wasn’t directed at me, but I’ll answer it anyway. The best thing my MIL ever did was kill herself. Her timing was, as always, HORRIBLE, and it has resulted in immense guilt for my FIL that I think he will never overcome, but it has also resulted in a sense of peace for everyone, the knowledge that there won’t be constant fights over who gets to do what, when and how, and also a much, much closer relationship between my DH and his father, which was impossible beforehand. Every single person in the family, with the obvious exception of my FIL, would say the same thing. You’re not a horrible person.
