I have a female friend, who routinely gets completely wasted on nights out. She's only recently started drinking, but now everytime there's a party or any social gathering, she drinks until she throws up and has passed out on a couple of occasions. She's 17, and will be off to uni in the autumn. We've just started to get really worried about her, because so far, she's always had someone responsible to look after her. If she goes away, there won't be any guarentee of this, and we're worried she'll end up getting herself raped or something.
Without physically stopping her from buying drinks, and supervising her all night, there isn't any way for us to control her, she won't listen. She's normally quite quiet and innocent, but is fairly immature.
A few nights ago, we had our prom, and she got thrown out after she was sick several times.
Any suggestions on how we can stop her acting so stupidly? I'd normally say that it was her own stupid fault, and that we should leave her to it. At the moment the worst that has happened is she's thrown up and made a fool of herself. However, none of us want her to continue behaving like this when she's at uni, because she'll be much more at risk without us keeping an eye on her.
