Trauma is part of life. So is resiliency. Trauma is not simply an event itself; trauma is in the nervous system. When our nervous system senses danger and threat—and this is different for every system—our primal, instinctual responses are activated as mechanisms to protect us and prepare us for survival. We are biologically programmed to fight, flee, or freeze in response to a perceived inescapable threat, and the younger we are, the more likely something is to be perceived as an inescapable threat.
