Wii- this made me cringe. I ALWAYS told my teens - "no matter what, no matter where - if you need me - I'll be there" if they'd drank too much - I would pick them up or pay for a cab or whatever. That they could call anytime. I might be temporarily pee'd off but I would come.
I think you need to acknowledge your daughter's feelings of fear & abandonment (you did) & tell her that she needs to phone you no matter what - you are there for her.
Voldy (first typed this as Coldy) is insane. This treatment of your daughter is abuse.
