Who are you hurting with your drinking? Your self, most obviously. But what about the family you mention?
I don't mean this as a criticism in any way - I did plenty of damage to those I love the most with my drinking. But in the it was the leveridge that I used most to finally quit forever and for good. You're lucky to have a family, there many of us who don't have that kind of leverage to help us get sober. Focus on them and what you can do to finally take care of them in the way that you know you are able to do. Sobriety is the only way.
