I thought I was the only one with the same problems that you have, when I quit drinking. I wasn't. Many, many, many of us could write the same stories.
I only wish I had quit when my kids were your kids age. You are giving them (and yourself!) a huge gift, getting sober now.
You do NOT have to battle this alone. In the early days, I lived on SR (I don't do AA). Sometimes, I still do!
