Hi Matt and welcome to SR
I don't have any experience with xanax or xanax alternatives, but I do suffer from severe anxiety and depression, and I know how you feel. I'm almost 3 weeks sober and I still experience brain fog or fuzzy thinking from time to time... this and my anxiety are not as bad as when I was drinking, but it feels pretty scary sometimes. I'm seeing a psychiatrist for my mental health and I'm on antidepressants. I'm confident things will start improving... as long as we stay sober
Wish you best of luck! Stay here, keep posting
