Welcome Tinatree, so sorry for your loss. What a blow. I come from a family of alcoholics too. It's in my genes. I have no brakes like "normal" people do. You've come to a good place here. We're all fighting this addiction that for whatever reason dogs us more relentlessly than it does others. It saps our will and never helps...though there's always that little voice that says you'll feel better with a drink or two. Nope.
Anyway I am glad to see you found your way here! Stick around! It helps
