anxiety in early recovery is awful. I remember it well. I did a lot of little things to make myself feel better. A hot chocolate from starbucks, a new pair of sheets or pajamas. Some new tea or a candle. Little self-care things.
Lots of sleep (if possible). Some exercise and good food. And self-talk. "of course you're anxious. you're changing your life. of course you want to drink. you're an alcoholic. of course it's hard, you haven't a clue how to live without alcohol but you'll learn" etc. I tried to consciously tie the unpleasant feelings to some pleasant action. Like "I feel very anxious right now. Maybe a walk will help". Rewiring my brain to look for something other than MORE WINE as a solution.
It does get better. Much, much better. But you HAVE to stay sober. every freaking drink I took just set me back to square one.
