Welcome to our family. I agree, you're very wise at such a young age - to see what needs to be done. I would never have come to that conclusion in my 20's. It took decades of destructive behavior to convince me I had to quit in order to save my life.
I had no support or understanding from family at all - they considered my drinking habits to be the result of a character flaw, I guess. ("Just say no" & all that.) Friends tended to tell me I wasn't that badly off - they had no idea how horrible it had become. So when I found SR it was just what I needed, though it took me a few months to get up the courage to quit. It was the advice, support, and love I found here that convinced me my drinking career was over.
Please keep coming back & let us know how you're doing.
