 Lenore C. Terr, Childhood Traumas: An Outline and Overview, 148 Am. J. Psychiatry 10, 11 (1991) (defining childhood trauma as the impact of external forces that “[render] the young person temporarily helpless and [break] past ordinary coping and defensive operation…. [This includes] not only those conditions marked by intense surprise but also those marked by prolonged and sickening anticipation.”); Judith Herman, Trauma and Recovery 33 (Basic Books 1997) (explaining that traumatic events “overwhelm the ordinary human adaptations to life…. They confront human beings with the extremities of helplessness and terror.”).
