Oh bless you. That was very brave, admitting that you needed to stop and doing something about it. Don't underestimate the strength and courage that that took.
I recommend reading The Unexpected Joy of Being Sober by Catherine Gray. That book really helped me, as did The Sober Diaries by Clare Pooley. There's also a really good MN thread for support in living an AF life - latest one here: The continuing support thread for living alcohol-free. Everyone welcome. | Mumsnet. I've found it incredibly helpful.
There might be some hard times to come, when the wine witch calls you and tells you that it will be alright this time, that you can moderate, you can have just one... Don't believe it. Keep on going and it will get easier with time. Think of how much better you feel in the mornings after not drinking.
I also recommend downloading a sober tracking App. The one I use is IAmSober (others are available), I use the free version. It's very helpful, especially the bit that tallies up how much money you have saved by not buying alcohol.
It might also be worth looking into some counselling for the issues that made you want to blot out the pain with drink, if you haven't already. Lots of us, myself included, drank to numb the anguish of history. Sadly that is still there when the drink is gone. But it is possible to learn to life, without drink as a crutch.
Very best wishes to you. I hope you have lots of happier times to come. x
