I think there are a lot of "normal" people who also have issues. Some of them with the problems I have. In many ways I look at my sobriety as a big opportunity and a gift. I can now finally sort stuff out without drink getting in the way. And if I hadn't got to the point of drinking starting to ruin my life... I would have bumbled along with my problems and they would have got worse.
I saw a hypnotherapist when I first stopped who told me "your weakness will become your strength". At first I thought, "what?" but it's kind of getting that way. He also told me to go to AA.
I think a lot of people when they stop drinking need to some sort of recovery/work on themselves. As I drunk to deal with feelings, patterns of behaviour.
It's also normal as others say to mourn your past, it helps us start to let go.
