im probably gonna trip on the stage or something or forget to go get my actual diploma afterwards also the all night party... which i'm probably gonna sleep during
that's probably all i can do... but man, with graduation rehearsal at 12:30, actual graduation at 6:30, and then the all night party from 10:00 till 5:00 am... that's a lot
Honestly, it can be pretty nerve-wracking beforehand but it goes by quickly. We just sat around for most of it listening to speeches and then each row was up for like five minutes each grabbing our diplomas and hugging teachers on our way back to our seats. The actual ceremony was over before I could even freak out about it.
The best advice I can give you is that if it's really worrying you, it would be best to just zone out and copy what everyone else is doing. And always have someone remind you to go pick up your diploma or set up one on your phone, just to be safe.
