You know you're not doing this for your family, so however you decide to get clean and sober is the way that will work.
And, spirituality is a broad topic. I started to do volunteer work when I first stopped drinking. I had no idea how much it would help me through lots of dark days. It helped me to get outside of myself and do something to give back. It helped me to grow spiritually. If you're not working, why not look around your community and see what you can do to give something back?
