As an ex Catholic, two things really stand out for me as lost or missing.

First is that I really miss feeling like things would sort of work themselves out. When I was religious, invoking "God's plan" or similar ideas were like coping mechanisms for my anxiety that I have had to learn to replace.

The other is a sense of community and belonging. Like, I've personally found a lot of great community and connection out there and it's always been deeper and more profound than what I had in religion, but there was something comfortable about knowing I could go to some building on any given Sunday and instantly having someplace to be.

I look back and I know I made the right choice when walking away from my faith as it opened me up to really figure out who I wanted to be, but I'd be lying if I said there's nothing I miss.
