Sally, I don't have children but I can still relate a bit. That overwhelming feeling of guilt and shame was what finally helped me give up alcohol and make my life better. I didn't really care that I was hurting myself, but when I began hurting my close friends, I just couldn't deal with it anymore.
I am sorry that your son saw the wine, but use this experience as a tool to aid your detox. Think of that moment when he saw the bottle and how you don't want to feel that way anymore. You
can do this Sally. We're all here for you
