A job will help. Al-Anon might help a LOT. Not only will it help with your recovery (and help you with the worries and stress you have over what he is doing), it will give you a circle of friends and get you out of your parents' house a bit.
I moved across the country with my second husband, who immediately went back to drinking himself to death. I had very few friends in the area, and nobody I could confide in at work. Al-Anon was an absolute godsend to me during that time.
I hope he stays sober, and that you can rebuild your marriage. But rebuilding you has to come first.
Hugs!!
