You poor thing. I'm not going to put the You Tube Video up here, because people can see it all over the internet.
Sorry you had to find out the hard way that no amount of preperation can 100% protect you from panic brain.
I'd feel really badly for you, except this is one blip on the radar and if you go on to do other things, people will forget all about it.
Fill the rest of your life with acomplishments and important work.
I'd feel worse for you, but you're young and beautiful and probably have an adoring family and the scholarship for winning your State pagent probably has you pretty well set up, and being jealous gets in the way of a lot of my sympathy.
Anyway, chin up and please don't let this moment define the rest of your life, because that would be really stupid.
