This site is clearly designed for adolescent girls to use themselves. It's a good overview of some of the common emotional issues in the early teens, although I suspect that young people actually dealing with these issues may find it a little patronizing. I did really appreciate the fact that they treated self-injury as a topic separate from suicide--when I was that age, kids who self-injured were assumed to be suicidal, which isn't true and is certainly an obstacle to treating them.

This is a good page and covers many aspects of the teen experience. I am not a fan of a lot of clicking, and this page is essentially a page of links, but they all contain vital information that most parents are not even aware of, let along take the time to talk with their kids about. There is a survey that pops up here as well that is slightly annoying, but girls may enjoy participating in it. Just don't lose focus and forget what you were reading about in the beginning.
