Hi and welcome sobersub
some folks find all they needed to do was stop drinking and the anxiety vanished - for others the anxiety didn't go away or was even worse for a while.
Like you, my anxiety was pre existing before my drinking - it's one of the things that got me into drinking, so getting into recovery I had to look for other ways of dealing with it now I was a non drinker.
Have you thought about speaking with your doctor about this at all?
