Welcome to SR Howdy
I think it's great you're here and thinking about your future
We don't have a youth forum - we did have an under 30 thread tho - maybe someone will revive it for you
Try not to plague yourself too much with what ifs...much of that is out of your control.....the best thing you can do is to commit yourself to a new sober way of life.
Follow through with that AA idea too - I think real tangible changes and real life support will help.
You'll find a ton of support here - good to have you with us
