Hello D.!
My name is L. and I can relate to some of what you are dealing with. When my daughter was 12, she would cut herself whenever she felt bad. (The doctor's compared this do doing drugs.)
She matured early and had terrible PMS. I talked to my ob/gyn about that and we made the decision to put her on a very low dose birth control pill. That with her other medications and a wonderful therapist have really done her alot of good. She passed all of her classes after missing 2 months of school. (She was admitted to Peachford for the cutting.)
Her therapist also meets with me and my daughter's father. He told us that we have to make our daughter understand that we are the parents, she is the child and there are consequences for her actions.
I know it's easier said than done. If you would like the name of my daughter's therapist, I will be happy to give it to you.
I hope this helps!
L.
