Isn't amazing how the people in our lives that are suppose to love us the most are usually the ones who hurt us the most too?
If your ma is suffering from an alcohol problem, she is most likely putting you down to feel better about herself. She might be doing this unconsciously so I'd try not to let her judging drag you down (easier said than done, I know).

Also, I waited a good long while before telling my wife, back when we were dating, about my issues. :-) Don't let a label dictate your life. You are you, the one and only. The label just helps to focus treatment, that's all.

Good luck! Now go break some hearts. ;-)
