Terrified of Singing

Started my Intro to Music class today. Did some basic voice stuff. I was terrified. I don’t know why but the act of singing freaked me out a little. I have never done any singing in my life, so I was a little out of my league. I knew that going in, and wasn’t really worried about it. I have sucked at things in my life, and I don’t really mind making a fool of myself at the drop of a hat. For some reason this was different. Just got tight in my chest, a little trouble breathing, and a shiver all over. Terrifying, but a little exciting at the same time.
