Welcome Green! I'm glad you found this place and hopefully some of what is offered will be helpful to you!

I was sexually abused about the same age as your daughter. Two different forms actually, and believe it or not, the "non intercourse" was so much more devastating b/c of the person who did it. I trusted him, incredibly so. He knew my history, and still made this choice. Sounds like her father was the ultimate betrayal for her. My moods changed pretty dramatically, but ONLY around the people I felt truly safe with. At school. . .aside from some little things, I was more or less the same person. At home however, things were very different. I started wearing larger clothes to cover up b/c I thought that maybe if people couldn't see my curves and boobs and such, then maybe they wouldn't be interested and I wouldn't be hurt again. My accent didn't so much change as did my affect. . .the way I spoke and the manner of looking around constantly (checking) and never being able to look people in the eyes (shame). You need to get your daughter into counseling with someone who is skilled at dealing with sexual abuse and trauma. It doesn't sound so much that she has DID or MPD, but it DOES sound like she is dissociating, which is actual a normal response to trauma. Check around, find some counselors, and interview them. Ask specifically whether or not they have experience dealing with teenagers and whether they are experienced with sexual abuse. IF all else fails, check with Rape Crisis.

Good luck to you and keep us posted.
