The best person to ask would be her doctor. Then try to figure out and outline some sort of treatment plan. DBT is usually the most effective thing for BPD issues such as being manipulative, acting out, anger/rage, cutting impulsive behavior,, and paranoia. Unfortunately one of the problems with disorders such as BPD is there's huge amounts of resistance to getting help and going through the actual therapy which can be extremely beneficial if stuck with.

Medication can sometimes help ease anxiety and things but not most of the behaviour, but I would definitely have a serious talk with her new doctor, explain everything that's going on, get clarification on your daughters diagnos(es) and go from there.

I hope you're able to find some help for her
