wow before i even had your total question read i was going to say give her a second chance. but after reading all of it i would say keep your distance. although the girl needs help, she needs professional help. you arent equiped to do that. i know you probably feel bad for her, but you can't take on other peoples problems at the expense of yourself. you are wise that you know what her problems are and wondering what the choice should be. dont feel guilty if you decide to step out of this friendship. deal with friends problems you can relate to, like boy problems or parents getting on your nerves. that kind of stuff. i would be pleasant with her but dont hang out with her. and dont gossip about her. ok, the fight is over so no need to keep it going. if she asks again about being friends just tell her that being friends right now is not a good time. i cant commit to a friendship right now, other things are going on that needs my attention.
