At the moment there is a girl staying with us, who is supposedly my 'friend'. She has become awful close to my brother, however, until last night.

I was actually feeling tremendously left out, as she was in his bed a lot, and they had their little giggles and were always holding hands in front of me. They've been out together into town on a few occasions, and she has bought my brother lots of presents, like PC games, and she paid for him to get his lip pierced.

You can imagine how upset i felt , after inviting her to stay with me (we got on so well online) and now she's sleeping with my brother!

Last night we were drinking again, and i decided to talk to other people instead of being left on my own. I don't know what happened but this girl has just become out of control now. She screams (my Dad is staying elsewhere until she's gone, and i feel awful selfish for having her impose on us as such) in the middle of the night, strokes the TV, and her laughing is one of the most annoying i've ever encountered.

Something clicked in her last night, my brother was crying in his room- bawling in fact (so loudly) and she was slitting her wrists in my kitchen.

Her arms are now gashed all over and the situation has been awkward since. She keeps throwing things about, and she's actually gone to the shop now to get more alcohol.

I'm not actually sure what i am supposed to do with her.
