Sounds like you’re determined to make a healthy change, that’s good! 
For me I started by learning as much as I could about my addiction. I read a lot about it; I watched YouTube videos about it. There are podcasts about a bunch of different topics here:
The next step and the one that really started me working on it seriously was when I joined a recovery group in my city. This was the moment when I opened up to another person about it, fully. It was liberating to share my story with a group of people who’d been down the same road. (There are groups listed at the link I shared above, if you want to take a look. Many have online options available too if you can’t make it in person. The nice thing about online is you can find a meeting 24 hours a day! It’s great when you need something to do with the free time you have now from not being drunk - which you’ll notice is a lot )
Take it one day at a time Ryan & you’ll get there.
