How do i feel comfortable in a small church when i'd rather just blend in?

Well, you've already judged the congregation, so the only way to enjoy it is to have an open mind. I grew up in a small church and I loved it because we were like one big family. Yes, people can get in your business, but they will get into whatever you share. Set your boundaries w/them, invite new friends in your life, and wait and see what happens. You may be pleasantly surprised.
