Well, Nellie, if they keep cutting back on the consumption, maybe they will see that you are not the boring one after all. (Maybe that is wishful thinking.)
I, for one, know that I once was (and am now again) scintillating without alcohol.
I don't know what kind of options you have (like support groups) and what kind of dynamics are going on at home, but I would want you to have the right kind of support around you.
