How do you start?

Mama Bear

I’m in my mid 30’s and have never regularly gone to church. I grew up non religious and my parents never went to church or practiced a belief. I live on a military base and they have several different religions and services but I don’t know where to start. Do I need to talk to someone? Can I just start going on Sunday? I don’t want to look like an idiot and not know how to follow along with everyone.
