My DD (15) has had problems with her friendship group as 3 of them have gone up to her and talking about committing suicide and revealing their plans on how to do it. they are also self harming in front of her. She is finding it very hard to deal with, she has talked to the school and her dad and I. Her friends have also sent her nasty texts and comments on Facebook because she told the school.
How do I support her through this?
