Rant over- is there any way you could call her school and inform them of her situation? They might have a counselor take over if you tell them what's going on. That's unfortunate that her mom is unsupportive, she does need help. But there have got to be options for her. I'd say if the school route doesn't work, and you have reason to believe she's in medical crisis, you could even call the police.
I do think that they listen. Even if they put up a wall I think they listen.
If the mother is denying medical care then it is a form of child abuse/neglect. So while this isn't the first route to go down it could come to that point. I agree to contact the school but first could you contact her mother and try to explain?
