Less than a minute into my speech, I felt the shaking. A shiver in my legs became full-fledged tremors that almost knocked my bare knees together. I kept reading the words on my paper, which by then was visibly rippling. The students in the front row, seated inches from the open area where I stood, started to whisper and laugh. I couldn’t stop my legs from moving and I knew the whole class could tell. My face flushed red and the rush of heat triggered sweat.
