In my English class my freshman year of high school, we had to give some presentation on this book we read and I was so deathly shy to the point of having panic attacks. So the presentation begins and I start to sweat profusely, my hands start shaking and I slur my words.
It probably wouldn't have been so bad if no one had said anything, but some people pointed out my shaking hands and I could just see my teachers concerned face shaking in a way as to say "please, get it together" XD.
It was a sad moment in time.
