You are so young - how painful to read that you drink this way.
Trust me, you don't want to continue on that path. I totally understand that you feel as though you can't talk to your parents. I couldn't either when I was your age.
Could you talk to a counselor at school? Or, are you close to any of your friend's parents and maybe could talk to them?
Or, do you have a "First call for Help" phone line you could call?
Wishing you the best, and hoping you find a way to get some help now. It only gets more difficult when you are older.
