Hi and Welcome!
Good for you for recognizing that you need to change and that you want to live a sober life.
What worked for me in the very early days was shaking up my routine. And, I made some big changes, I had to. I removed a few people from my life who were toxic. That was something that I knew instinctively I had to do and did it immediately. I knew that a hard time of the day for me was early evening, so I went out for long walks after supper. That turned out to be a blessing in so many ways. Journalling also helped a lot. Another thing that helped me was to get outside of myself. Think about doing something in your community, some kind of volunteer work that will give you an opportunity to give back. I don't use AA, but it's a resource that helps many people.
And, keep coming here to SR.
