Thanks everyone. I now know you have to feel these things. if it's bad enough, I guess it's then it motivates you to do something about it. There's nothing different I can "do", for this particular feeling, I had yesterday - other than continue to not drink.
In a strange little quirk, I actually woke up this morning motivated to do something I'm working on for my job. If all I have right now is my career, I'm grateful for it, because I nearly lost it, so I may as well be the best I can. The rest will come if it's meant to, when it's meant to.
I will just have a cry here and there about the other stuff, lol.
