I hope you can help your friend get out of there fast. While waiting for the entire emancipation process she should try to find a part time job somewhere so she can show she has a way to support herself. As for her family if she can live with you or another friend until graduation (if she's graduating this year) that would at least get her away from that trauma.

If you haven't talked to a teacher or counsler yet you should because they'd be required to tell Social Services and they could help her get out of that house quickly too.

Hope things work out. sad
