"I Knew All The Answers,
But My Mind Went Blank."
Test = Rattlesnake
When you have a strong "inner saboteur" voice that keeps telling you, "You're no good. You're not smart enough. You're never going to pass this test," trying to convince yourself differently is really hard. If it was this easy, you would have already told yourself this and you wouldn't still be experiencing high stress and anxiety symptoms.
"Then I'll change my irrational thinking, right?"
Your conscious mind understands that a big test, interview or critical performance is not a rattlesnake. However, somewhere in your psyche you are carrying an inner belief that this event is a threat or danger to your well being and safety. Because of this "perception," which may be irrational, but perceived real in the moment, your limbic brain triggers a "protective" mode response to a critical testing or performance situation.
