I moved your post into its own thread. This way, you are more likely to get responses rather than have them lost and mixed in with replies to Angie.

One of our members here has a website about self injury that I think is an excellent resource. The Coccoon: Self Injury Pages Why don't you take a look at that, and feel free to ask any questions that you have here. We would be happy to help you and your daughter to understand and deal with this issue.
