I couldn't feel other pain in my body (I have a current shoulder injury). I could NOT let go of the thought pattern I was having. I caught myself rocking (something I almost never do). Anything that wasn't right was WRONG WRONG WRONG. I have felt completely exhausted mentally since.
If it was a meltdown (as I'm becoming more sure it was as I write out how i felt) then that means I've got to be a LOT more careful about environmental factors than I thought.
