I think you're in a place where you're ready for your world to get wider, you feel confined to what you know and tired of the same old routine and maybe you feel like there hasn't been any personal growth happening, and that can make you feel depressed.
One of my drinking triggers is boredom and frustration with repetition. I need change sometimes or I'll get depressed, and when I'm depressed I revert back to old coping mechanisms.
I agree with others who say therapy is a good direction to go in.. you may have exhausted all you can get out of AA for now.. The statement that you still feel a lot of discomfort with the world around you AND discomfort being around alcohol, makes me think there's a lot of work left to do... Because I think the goal, at least of MY recovery, is not to just stay sober, it's to get to a place where I feel good and alcohol has absolutely, positively, NO hold on me anymore!
