Well first of all welcome to psych central

I'm glad you were able to help her get into treatment. You can be supportive but it's really up to her to persevere and and continue treatment.

One thing that I strongly advise is to not interact with her when she's being abusive. If you are on the phone tell her that you won't listen to abusive talk and hang up. If she starts with abusive text messages do not respond. Don't go to her house when she's in one of her mean moods.

If she goes at you in front of friends leave if you can. She may be doing this from the bilolar or she may have other issues, and behaves in an abusive manner because of this

You can't help her unless you take care of yourself first.
