I understand what you mean. I was in treatment at 23 just last year and did AA there. You aren't too young and it's a disgusting horrible cruel disease that doesn't care about your age. I'm going through a hard time too now but just try to hang on. But no you're definitely not too young for AA. The people in those rooms, no matter what age they are, will get you. That's what I found anyway. Hope you get better, hang in there.
