What should I do about this suicidal girl?

It could be she is not even sucidal but craves attention. I used to cut but I wasn't sucidal for one thing. And theirs always way to call for help like safe to tell and what not. Maybe getting her conselours or something. She's too young to think of sucide so It may be bluffing.. Don't get too involved otherwise you may have similar thought process, get her help... Hope everything works out for the best
