Coming out of a shutdown

Last night I had a major shutdown, in response to family argument. From 4pm to midnight, I could not speak and sat still for at least an hour, without moving at all. Today I was the same from 6am till 9ish. Then I had zero energy and functioned on autopilot to do basic tasks like make breakfast and coffee. Words, when they came were low, monotone single words. My sensory tolerances were very low, and speech has slowly returned to me. I still don't feel 100%. I have been shuffling around, having odd 10 minute power sleeps, sighing a lot.

Do other people experience shutdowns in this way?
