I have an undiagnosed daughter who I think has autism / ADD. She has severe skin picking issues which I believe are caused by anxiety, and is really struggling at school with socialising. She is 15, in Yr 10, but only really has one friend dating back from primary school. She cries some evenings because she tries to speak to people at school but they don't engage and she says she doesn't know how to start a conversation or understand what people talk about. It's devastating not knowing how to help. Any advice really valued.
