I think for me, as I go through recovery, I have had to realize I never knew who I was before. I spent my 20's married and raising kids. I did as I was told. When I left the marriage, I started drinking a lot, so took on the persona of a party now. Now, I am getting to know myself, getting more comfortable in my skin.
But, I will say, through my own recovery and seeing others, most do become happier, more stable, better, once they are clean.
Hugs to you!
