Hi Brown Eyes,
Welcome to SR. I'm Anna, recovering alcoholic and I'm glad you found us. You can find lots of support and understanding here.
You're right, you need to look after yourself at the moment. You can't control what will happen to your relationship in the quitting process, but what you can do, is stop drinking today. I know when I first stopped drinking, I badly wanted to mend things with my daughter and counsellor told me I'd have to be patient. Only time will tell what will happen.
You can stop drinking today and start to feel better. We're here to help. Hang around and be inspired.
Love, Anna
