I remember doing the same thing you talked about: "making it through the day" until you can get the 6-pack. It's a vicious, vicious cycle and there's nothing pleasant about it. We don't care much sometimes about dying because we're not really living.
I agree that starting back at square one (one day at a time, one hour at a time) is the only way to go. You might be scared, anxious, bored or any other emotion, but emotions won't kill you and this will. Itching can be a sign of liver issues and the pain you're having doesn't sound good at all and as you know, it will only get worse if you keep drinking (ANY amount). The good news is that it doesn't have to get worse and can even get much better.
Get through today and post tomorrow, OK? We're pulling for you!
