Strange confrontation action symptom


So I confronted someone today that has caused years and years worth of trauma for me that still affects me today. It got extremely painful so before they could finish what they were saying I blocked them. Afterwards, I was freezing. Like shaking, cold to the touch, utterly FREEZING. Could this be a trauma response? Possibly another way your body releases all the adrenaline from the stress of confronting someone? Ever happened to anyone else?
