I was nervous as well because I didn't know much myself. They were very welcoming. I starting going to Church in late January. While, I was reading the Bible on my own, I thought I could use some help. I belong to a group that is a Right to Liberty group and the pastors wife was there. We happened to be talking about how religion has been infiltrated and how people were leaving their church because of the mask mandates. The pastors wife spoke up and said her Church was a good church and no masks. So I started going there about a week or two later. So, this is what I did. I sat in the back of the church and observed. Things are on a tv monitor so you can recite the prayers along with everyone and when we sing its displayed on the monitors. When they say stand I stand, when they say sit I sit. You do get the hang of it. My church is very small and quaint. Work on your relationship with God, talking to him at home, it may feel awkward at first and you may wonder "am I doing this correctly," but that soon goes away. You got this.
