You didn't say how long you have lived with "Mom"
In my experience with an alcoholic, the more I opened up and let my fears, dreams ,worries out to him, it came back to slap me in the face, so there went my self esteem out the window.
Al-anon didn't work for me ,but it may work for you, it's at least worth a shot.
My alcoholic ex never had a good word for me, I never did anything right. It was a very sad and lonely 18 years. If you don't have to be there, then don't.
I realized after I moved out that I suffered from depression, low self esteem and co-dependency. I have been away from him over 5 years now and I have improved, but it has been a slow process.
Keep coming back and I as I'm sure others will help.
Take Care
