Ok, so you're 15. No state will emancipate a 15 year old, but if you're being abused, you can contact child welfare and they'll place you in a foster home.
If you are 22. You should be able to stand up for yourself. Get a job and support yourself. Then you are only answerable to yourself.
if your under 18, get a court order: emancipation. If your really 22, then move out, distancing yourself from her, for a while.
Your profile says you're 22 - you can just move out.
Mybad , I didn't see that but that's not my age
