Effie, hello and welcome to SR
You sound like there's a lot going on for you right now. I was in the same position as regards the family background of alcoholism and the hurt I felt. I decided to make that commitment to quit for me and my kids so I could break that cycle. Nearly a year later, I can tell you how much better my life is. My children are happy and our relationship is better than I could dared to hope for.
You can do this. Take that step towards the life that is waiting for you and your child. You won't regret it xxx
