I feel for you, PM. Lots of good comments here.
The best thing you can do is to stay sober for yourself and your child. The stress and anxiety will continue to lessen the longer you stay sober and work on healthy stress buster coping skills. Children, at any age, pick up on parental stress and it’s only natural they want to avoid it. It doesn’t mean a child loves a parent any less.
See this as an opportunity for self growth and improvement
Remember this too shall pass, and drinking will only make matters worse. I hope you will post here as often as you need for support.
