"Hello I am posting here because I have two years and two months sober but lately I have been questioning if I really want to be sober. I'm an IV meth and heroin addict who is 21 years old."
I am an alcoholic who got sober when I was 22. I am wondering if AA is even the right place for you? I would have no clue as to how to help you. I have absolutely no idea of what it is like to travel the road you have been travelling.
I can give my opinion, which really echoes the advice of miamifella, but I have no actual experience of any value to you.
