Who will I talk to when I go to church?

Hello everyone, I have been researching Christianity for a long time. And now I have decided to become a Christian. When I enter the church, I feel better and safe and happy. But for some reason I'm afraid and hesitant to talk to someone from the church. For example, I want to marry a Christian. I want to wear a cross necklace around my neck. I want to talk to god for hours in church and pray. But there are so many things I can't do and I'm sorry. What do you think?
