You've been going about your life business as usual when all of the sudden this new opportunity, or thing popped up and you have to deal with it:
A difficult conversation with your boss and you're freaking out.
You started an online business but you suddenly freeze up with imposter syndrome and questions like "Who are you to do this?"
You want to perform for an audition, create a video, or speak in front of a crowd but every time you think about it you start sweating and feel like you're going to pass out.
