Welcome Lateralus,
I was very scared too, when I stopped drinking. I couldn't imagine coping with life without alcohol. But, when you step out of the cycle you will find that it's not so scary. You'll feel better in every way and you can learn healthy ways to cope with life.
I had to make some lifestyle changes in order to stay sober. I changed my daily routine so that I was physically active (outside walking) in the early evening. That helped me a lot. I got rid of a few toxic people in my life which, surprisingly, opened the door for some wonderful new people to enter my life. I couldn't be around alcohol or people who were drinking for most of a year and that helped me establish new routines.
You will find lots of support here, so keep reading and posting.
