I have rage issues with my BP. Can snap at any given moment and it's like I don't care who is in my pathway. My husband has set up a "special place" where I can go to Let out the rage. Lots of things to break there (my favorite..hehe). But most importantly your daughter needs to learn how to channel this rage in a productive or safe mannar. Lots of great advise has already been offered so not much left for me to add....all are great ideas. Make sure you "remind yourself" that it's the "condition she has" and not her that is striking out.
