I was a foster mom for 8 years. I have seen a lot of children have detatchment disorder. Kids are afraid to be loved and to love back because once they do their surroundings will change. I know it's hard but she just needs to keep being reminded how much love you have for her and if she is not in counseling she "needs" to be. They need to have an independent outlet that has an unbiased opinion.I would also try to get her involved in a good youth oriented church & youth group where she has more positive people her own age around her, Good Luck.
