Yes, I struggled with horrible guilt and shame for a long time when I stopped drinking. I hurt my family and I wasn't the mother I wanted to be. I had to learn to forgive myself and believe me, that's not easy. Nor did it happen in one fell swoop. It's something I had to do over and over again.
When I was really struggling with this, a wonderful person here at SR suggested that I journal about my feelings. I really didn't want to do that. I didn't want to see the words written down. Finally in desperation, I began to write and I kept on writing for most of a year. As I wrote about the feelings, they lessened. It helped. And, when I was finished writing, I burned the journal.
