Hello,

Recently a very close friend of mine admitted she was starving herself and has been making herself throw up any food she eats.
Tonight while she was drunk with a friend, she very proudly told me she weighed in at 39 kilograms. She's 15. She's already at the stage of fainting and having frequent blood noses but for some reason no one seems to notice or speak out about it, not even her parents.
At this point I'm terrified and don't know what to do because I know soon her body is going to start collapsing.
I'm unable to talk to her school about it as I live over an hour away, and as I said before her parents don't seem to notice/care about what's going on.

Any help and/or suggestions is greatly appreciated, thank you.

Side notes: She also suffers from depression, anxiety and body dismorphic disorder and is seeing a psychologist
