You are so wise to be looking for a solution now, as opposed to this slow learner. It is not always easy to face these things or make sense of them, especially when we're young.
You are not too young to check out AA or NA. A lot of them have newcomers or young people's meetings, but if not, you can still go to the regular meetings, share your thoughts, and learn more. Just stick close to the women.
You'll be in my prayers for some enlightenment. The elevator only goes down and you can get off anytime you are willing and minimize the wreckage. Living sober is a wonderful way to live.
Edit: My friend's husband got sober when he was 15 and never looked back. He's lived a full and amazing life and he's still young (42)!
Hugs to you,
Lisa
