Low and behold! I discovered that Krista Tippet interviewed Bessel van Der Kolk, MD for her podcast "On Being" that I've been listening to recently. I am currently reading his book The Body Keeps the Score.
In the interview, he makes the following statements. My personal responses follow.
At times, there are parts of me still engaged in resolving the moments of secondary traumas that stand out. I frequently discover that I am trying to solve the unsolvable problems of the toughest shifts that I faced, mostly as a shift leader. Part of me is still trying to determine how to simultaneously help a child realize that they’re holding themselves to an unrealistic expectation, answer a call from a cell phone, and respond to a person on walkie. I am aware that these interactions are not presently making demands of me. Yet, I can take myself back, with ease. I can yet again sense that state of palpable panic, nearing utter disbelief.
