There is always hope. You mentioned that at one point you were doing AA meetings, have you considered going back?
As Carl mentions, the real question is what are you willing to do to get sober. The bottom line is that drinking is the cause of all your problems, and the solution is to stop drinking. It sounds as though you haven't accepted that you are an alcoholic as you have continually decided to keep drinking, even in the face of losing your family.
Make today the day that that all changes. Accept that you cannot ever pick up the first drink. You have the choice.
