You can definitely be normal.
Reading your post, the vibe I get from you is "I've been sober for months and months, but I didn't really do that... it was a requirement of my circumstances so who knows what will happen when I leave."
But
I read it and my (civilian) reaction is, "Holy ****, this woman
volunteered to literally
go to war in order to stop drinking. That is one tough as nails lady."
Definitely it will be an adjustment... but I think by framing it to yourself as something that was done for you, rather than a decision of your own, you unfairly set yourself up for more self-doubt than you deserve. You did this, it wasn't easy, but you meant business and made it happen. And now you're going back with a fresh slate, a chance to develop totally new routines and patterns, and all the early withdrawal stuff will be behind you.
That's awesome!
