Hi Renvate. When I was still drinking, I thought that I drank because I had low self-esteem, was depressed, and was angry & frustrated with people around me. I thought if I didn't have those problems, I wouldn't drink.
After I quit and got some sober time, I realized I had it completely backwards. I was depressed, angry, and felt bad about myself, because I drank too much. Once I quit drinking and got some good sober time in, many of those issues disappeared. Some problems didn't just disappear, but I had the clarity of mind to work on improving them, and they improved.
I really believe we can be the people we want to be, and build the life we want, and putting the booze down for good will make that possible.
