Welcome!
Without knowing more of your background, I'd say read around and see what resonates with you. Ask any question you need to.
There's the physical aspect--recovering from alcohol takes time. Eat what you need to, drink lots of water, get some exercise if you can, and talk to a doctor if you're concerned.
For me, the emotional part was much harder. Learning to live without alcohol as a way of dealing with life and as an identity. There are different ways of dealing with this, so see what helps you.
You're not alone.
And getting sober was the best decision I ever made. Best wishes to you.
