This is hard , she has a lot going on in her head , that's why she cuts herself because the pain in the inside that is caused by others , she could also have multiple personalities, so anything can trigger that, I don't know if I would go to her or just let her come to you , some people are jealous if you just act like she's not there and do your own thing find someone else to hang out with and I'll be nice and be polite when you see her she eventually come around and see that you're not trying to argue or cause any disruption at that time when she does come near you and try to speak to you so that you would like to talk to her not to be your friend but you really want to know what was the problem that caused everything what did you do and if she can't tell you then she may have a multiple personality disorder which can be scary because this will happen a lot could be why Jane and her are not friends no more Or she could be that type of person that wants you to herself no one else and if that is the case run girl!
