Hi, I'm sorry if this is posted in the wrong place.

I'm in highschool, and a girl I know (who has always been a bit strange) is clearly very sick. Here's the short rundown-
- She thinks she's a werewolf- although the term werewolf is insulting.
- Her "other half" is the wolf part of her who shares her body. This "other half" has her own name, her own voice, etc.
- A lot of her fantasies are based on the TV series Charmed. She claims that Charmed is based on real life.
- At night, she supposedly goes "hunting" for demons, so she may vanquish them.
- Her boyfriend, is 19, a "good" demon, and is undercover as a 25 year old cop so he can spy on the government, who is out to kill "their kind"
- Today she bit a friend of hers- literally bit down on her wrist and left a big red puffed out mark. Her friend didn't say anything but a close friend of both of them decided that something should be done- I went with her to guidence, our counselors weren't available, so we went to the nurse so the girl could have her hand checked out.
- later in class, the girl was crying because she was afraid she would get in trouble for biting someone, and she kept mumbling something about how the school is out to get "her kind."
- Then the girl proceeded to threaten whoever it was that reported the bite.

Ok so that wasn't so short. her fantasies go a lot more in depth than what I wrote though.

...

Should I just be leaving this alone, or should I try to get this girl help? The friend who went the the nurse with me, said she's known this girl since elementary school, they were best friends growing up, and when they entered high school, all these fantasies began. She didn't know what to do, so she went to her guidence counselor who put the girl in group- a support group for troubeled kids at school. From what I know, they sit around and discuss things such as drugs, parties, alchohol, violence, etc. It really is no help at all. We do have two school psycholgist- should I go straight to them? will they do something to help?

or should I just mind my own business?
