 In that moment, I don't consciously make the choice to go into fight or flight or fawn or freeze. I don't choose that. My brain is in its stress response system already, and it decides for me which defense mechanism is going to keep me safe and keep me alive. So it's a very primitive function of the brain. Even if I'm not in a situation that is physically threatening my safety, my brain is going to act in that way to protect me.
