Hello ggg,
sorry to hear that things are that bad! I think I'd be considering boarding school too - all girls. The sort of place where a sneaky cigarette in the toilets and a bottle of Malibu is the height of rebellion.
It's kind of reassuringly normal and young, that she went and got someone else to help her face the music though.
I just remembered a girl at my school who did the most huge rebellion, dropped out of school, rough pubs, dreadful boys etc. She's now a university tutor, happily married to a nice man.
I guess the big question is, how long will it last before things get better?
