In my own experience...it just took time for it calm down. I just past 6 months sober and (Thankfully) my anxiety has pretty much leveled out.
That being said...You just need to tackle each day as a individual day. Or hour..Or minute...Whatever it takes.
I found hobbies helped too as a distraction during the unpleasant urges to drink (Which have also gone away for the most part)..Music helped for awhile. As did breaking out my old school video games. Replaying the original Legend of Zelda was a blast...Really felt like a kid again.
Diet...Was important too.
And well... Get involved in the recovery groups that are out there.
I wish you well. Manage the day in front of you. That's all any of us can do really.
