I have been in a torpor for five straight days, lacking the motivation, the interest, to do pressing work, doing only the most immediate that cannot be put off. I have not had such a thing at any other time of my life. It is not a physical ailment that is the cause, it is not mental fatigue, it is not fear of the work to be done, or busyness with the unimportant; it is some psychological avoidance. It is "1. a state of mental or physical inactivity or insensibility. 2. lethargy; apathy." It is torpor.
