Freeze
Another response to danger is your body hitting the pause button altogether. The freeze response involves becoming immobilized or “freezing” in response to a threat. This can involve a state of paralysis or being unable to move. It’s thought that this response might have evolved as a way to avoid being noticed by a predator or to remain still in the hopes that the threat will pass by.

I would suggest emailing improv groups around you to see if you could join a class that’s supportive. Make sure to ask the teacher ahead of time so you can get a feel for if they’d be good for you or not and if they’re willing to work with you. If you could take a friend that’s interested as well, that would help for you to work with someone you trust.
Jon Stewart said that he did the Big Mac thing to make up for insulting the food that goes on Trump’s plane, lol. He was sucking up which makes it funnier to me.
