Help for prom?

Today is my prom for um.. when you're done with high school? 😳🤔 Honestly, I never thought I'd get this far. I always wanted to drop out and I thought i would *die* after high school because life didn't make sense for me,i t seemed pointless. But two years ago I started dating a friend I made when I was ten and he makes me think about the future in such positive ways 😊😄, he helps me with things that happened to me, he's my best friend, my love and sometimes my second mom 😂 and we're going to prom together😍. The thing is, we have both the diploma thing and the dancing/eating thing today. And I have social phobia... but when they give out the diplomas, we'll be (200 graduating ) on the stage and there's 500 people watching us in the auditorium.... we're not supposed to move, I.e. no stressed leg shaking or hands moving around because panicking or whatever. How do I survive tonight? 😳😐😓 Also, how were your proms? 🙃
