How to calm nerves over presentation?

I need all the advice. I have TERRIBLE social anxiety and in my group for class we have to do a presentation and each of us has to speak for 5 minutes. There’s some “popular” kids in my class and I feel like the nerves of that is adding to my anxiety as well. I mean I wanna get it over with but AHHH😭😭😭 I know in all reality no one cares. But my head likes to play games with me that everyone cares if I mess up.
