I'm sending you a big hug, too. Alcoholism is such a terrible, terrible disease.
There are already a lot of great things that people have said/suggested to you, I'll just add that my teenage children go to Alateen and it has made a HUGE difference for them. And some of the kids who come to the meetings end up bringing their little brothers/sisters to the meetings, too, because they can't leave them at home with a drunk parent.
I'm so sorry, sixers. And at the same time I find myself feeling so grateful that there are amazing teens like you in the world. I hope the so-called adults will step up and deal with this situation since it's not supposed to be your job at this age, but even if they don't you have us, Alateen and your guidance counselor. Keep coming back!
Sending you hugs,
posie
