I feel out place

Whenever I interact with people outside of my small circle of friends and family, I feel like such a freak. I never know what to say, and if I do find some combination of words, it comes out wrong and sounds foolish. I wish I had a script or something, everyone else seems to flourish socially, even the people that seem to get perceived as shy by me. I know I can’t be the only one but it feels so isolating and I wish I was different 🙁
