Had someone done the above to me when I went through that stage I would have found a way to kill myself as fast as I could. Actually if someone tried that today I'd be getting the heck out of here. That won't help anyone, esp not your relationship. There are many inpatient treatment facilities that you could inroll her in. There is one for teenage girls called Mercy Ministries that raises a lot of the cost with donations. It is a Christian organization though. If she isn't in danger anymore either try increasing how often she is in therapy or changing her therapist since she doesn't seem to be getting what she needs. After I was raped I held a lot of resentment toward my parents for not protecting me, esp since when it came out they also didn't support me. Maybe sit her down and tell her you are worried and ask why she is acting out.
