text: Just let her know your there for her, if shes got nothing else your obviously a good friend and a good start!  If your still in school talk to a counselor for her if she won't help herself you can remain anonymous and they will talk to her about her problems and put her in touch with the people she needs to fix her family situation (social services, police, etc.).  I've listed a site below as my source with number so suicide hotlines please give these to her.
