its very good that your daughter decided to tell you that. some kids cut just to see what its like, but some cut, and then cut again, and soon it is like an addiction for them. you should sit her down, and ask her to honestly tell you what has all been going on, and hugs, she may not want any at all, or she may like them, but even if she acts like she hates it when you hug her, she truly needs someone to comfort her. just always comfort her, and don't leave her be. tell her how much you love her, and if there is anything you can do. i am 15 and struggled with cutting for over a year, and am giving this advice out of my own experience. i would have loved to have comfort from my mother, but she just broke away from me and wanted nothing to do with me or my problem. so, coming from a teenager, try to be there for her, its all you can really do.
