Thank you all for your comments, they have really helped me.

Moodycow: I am not a cutter but have an eating disorder which can be and is a form of self-harm for me. She knows about my eating disorder and also knows that I have been hospitalized twice for it. The first time, I was actually having horrible urges to cut because they took away my coping skill of not eating. They allowed me to have a rubber band to snap every time I had the urge. I snapped it quiet frequently the first few days. I don't know why I haven't thought about getting her a rubber band or something similar to use in place of cutting.

Her T finally called me back today and told me that I should go in her room and search it for objects that can be used to cut with. Also told me that I need to tell her dad. Of course my daughter doesn't want me to tell him because she says that he will yell at her. He doesn't understand mental illness of any kind and doesn't want to understand it either. Knowing this, I understand why she wouldn't want him to know. He probably will raise his voice and she will have to deal with that.

She did admit to cutting to the FSL and counselor at school today after being told they knew she was lying about how she got the scratches. She also admitted it to me and said that she hasn't done it for awhile and doesn't plan on doing it again. She said that she doesn't want to talk about it ever again and that she hates school, the counselor, the principals, and whoever told (which was me).
