Take some facts that are commonly known and accepted. In this case the body state (food, sleep, exercise, illness, etc) influence your state of mind/emotions. This is the hook that establishes trust.
Conclude what is obvious but completely unhelpful: you have to live a balanced life. No shit?! But present it in a long and pretentious manner that will make your readers have a ridiculous Eureka! moment.
Then add the twist. The completely unproven and unsupported theory that sounds good:
> instead of saying “I’m scared,” she blurted out: “I’m experiencing high arousal from uncertainty.”
> “Anger” is a cultural concept
Choosing different wording and expressions for emotions will not change how you feel or how you act. It will only make communication difficult with other people.
EDIT: a rose by any other name...
