FF,
Good to see you back. If you truly believe you need outside help, such as rehab, please tell your parents. Or is there a school counselor you can talk to? I know you had trouble finding AA meetings there, but maybe the school can point you to some support group.
Your last post was riddled with shame and you really wanted to stop drinking. It will be hard doing it alone, with everything else you have going on. You must find help
