Can you be more detailed in what you mean? Abuse in what way? What kind of emergency? If you're saying she's dangerous and your life is in jeopardy, then you need to get away from her. We don't know what country you're in, but if this is the case it's the time for friends or other family members or gov't organizations or non-profit organizations that help people in immediate jeopardy. If it's not that but something else, then more explanation will get more responses.
Is there a distress center that you can call for help?
