It sounds like perhaps you and your daughter would be better off not living together. I would look into as other posters suggested perhaps giving your parents guardianship over her...or I am sure there are other options. I really hate to say that because I like to think things can always be worked out but it seems like for your wellbeing and mental health you need to get away from her at least for a while.

She needs some kind of therapy or is simply going to have to face the consequences of her actions...its seems like she thinks she can just do whatever she wants with no regards to others and she is likely to get in trouble with the law even if its not from you calling them if she hits you. But that is just my opinion...I am certainly not an expert.
