Summary

A musical theatre performer will experience a variety of negative emotions after being rejected throughout their career. More often than not experiencing a few at a time. The severity of the emotion depends on the audition's relevance to the performer, at what stage of the process they failed and the reason for being rejected. These factors determine which emotions are felt and their duration. 

It's human nature to take rejection personally but advantageous to ones self-esteem to realise that the majority of the time that's not the case. If you have performed to the best of your ability you can hold your head high. This comes from experience and a certain maturity leading to positivity and confidence and is a good coping mechanism.
