I'm sorry to hear about your daughter Katheryn ... and as i am not a parent myself (although do deal with self harm) all i can suggest is just being there for her. Let her know that you can and want to help, but also give her space and give her the choice whether or not she wants to talk about it. Unfortunately i dont think that there is much that anyone can ever really do for anyone else about it, ultimately it is their choice, and you just need to provide her with the right resources - as you are already doing.
