It will get better, keep going. It will probably take a lot longer than you would like, but it's worth the wait, trust us.
For organization, have you gone to flylady.net? She's good for step-by-step organizing. It's kind of a dated website, you may be able to find one you like better, but flylady really helped me get more organized and let go of stuff. Lots of tools and steps to take. Baby steps.
Getting my house organized really helped with the brain confusion, too. To be fair, though, I did the organizing while I was still drinking. It was one of my many anxious habits to keep stuff I don't need.
