If anything ever illustrated perfectly the profound fear that many have of speaking in public, then it is this short video by educator Mikael Cho and directed by animator Robertino Zambrano of KAPWA Studioworks.

In their own words,

Helpfully, they not only explain what is going on inside your brain but also give suggestions on how to calm your stage fright.
