AA wasn't for me back at your age / stage either.
Then, almost ten years later, it was.
What changed?
Well.... things got a fair lot worse.
I'm not a hardcore AA. In fact, I haven't been to a meeting in a couple months. But the program and its people have been a tremendous tool in my overall sobriety toolkit.
For me, it wasn't AA or therapy or exercise or SR or meditation or spiritual pursuits or changes in my lifestyle or friendships or activities or interests.
It was all of that.
And it has been so, so worth it.
You can do it.
