Welcome Katman. Another AA success here. I was three months sober on my 23rd birthday. There are really good young peoples groups around these days, great fun to be with. However it was older, wiser, heads that helped me get sober. I would make use of both.
The hardest thing is to imagine what life might be like. When you get into problems young, like I did, doesn’t give you much positive life experience to go by. All I can tell you is it has turned out quite differently and way better than anything I imagined back then. Give it a go. Your new life awaits.
