Church First Timer

As the title suggest, Im attempting to go to church for the first time.

I was always agnostic and never really understood religion as a child and my whole family except my mom are non religious

As of recent I’ve been dating my bf for about a year and he wants me to go to church with him and his family. They are pretty religious and go every single Sunday.

I’m incredibly nervous and church is something I have alway been insecure about because I feel as inadequate and that his family will see me as undeserving or bad because of my relationship with religion.

I have been more open to going since I can learn on my own about religion.

As a kid I would be embarrassed to do anything infront of the church and would avoid going in line to receive blessings and eventually my sisters and I stopped going in our childhood since we were too anxious and embarrassed to receive our first communion. Public anxiety was always so bad.

Idk what to expect and my bf has gone over some things I need to do like cross my arms walking up for blessings? But idk what that means and I’m so anxious that I’m going to make a fool of myself and everybody will know I’m not a follower the way I should be. I feel inadequate.
