High school stressing me out (need advice)

im in a mess. I’m currently in high school and I’m stuck in a situation that’s giving me so much anxiety..

So, I have this oral exam/memorization task that I was supposed to submit to my teacher two months ago. Back then, I actually had the chance to do it, but I completely panicked because we had to perform in front of the whole class. IN FRONT OF EVERYONE. I got so dizzy and my mind went totally blank, so my teacher told me I could do it some other time at his desk in the staff room instead.

Fast forward to now... I still haven't done it.

I have a few classmates who haven't submitted theirs either, but every time I ask them to go with me, they always make excuses. Most of them honestly don't even care about the grade anymore. But I DO care, I still want that grade! The thing is, I’m way too embarrassed to go alone to the staff room. If I wait for my friends, I don’t think they’ll ever go. but if I go to the teacher by myself, I’m terrified that I’ll suddenly forget everything I’ve memorized the moment I stand in front of him. My social anxiety is so bad that even if I know the material by heart, I’m scared I’ll just freeze up and embarrass myself again

What should I do? Should I keep waiting for my lazy friends so I have a "moral support", or should I just suck it up and go alone? Any tips on how to not freak out in front of a teacher? help me
