Morning Tatsy,
I think it's best to just focus on what's in front of you. Once you've got a solid foundation without drinking, you can tackle the rest of it.
I've found lists very helpful. I write down everything that I need to do and categorize them by timeline and importance, and then pick a few for the day, then week, then month. Then I make myself do whatever I don't want to do the most, first. Once it's out of the way, I usually feel better about doing the rest of it.
Go easy on yourself, you've been through a lot and your body needs rest. We are often so hard on ourselves, way harder than anyone else would be. Practice self love and forgiveness, that's what you really need right now.
