" Trauma has become so commonplace that most people don't even recognize its presence. It affects everyone. Each of us has had a traumatic experience at some point in our lives, regardless of whether it left us with an obvious case of post-traumatic stress. Because trauma symptoms can remain hidden for years after a triggering event, some of us who have been traumatized are not yet symptomatic. "
