" I am interested in maintaining my mental health and sobriety and spirituality, but that's about it."

That is enough for you to do. Good work. I also not interested in football (it is boring, violent, and over hyped). I not interested in Religion for the reasons I gave. I also not interested in work, for I want to remain "Retired". I am selective about women too.

No need to feel empty. You are doing well.
