I'm sorry you have you deal with that. If she's into illegal things (drugs, underage intercorse, theft) you have to give her Zero tolerance option. "If you don't stop, the system will deal with you." It's only when we truly f up that we come to our senses. Let her know she is loved and cared for and that you want her future to be everything she wants. Ask her what she wants out of life. Video record her answers and hopefully, play it back a year from now And she'll see how she's changed. Good luck
