When I rest I feel utterly lifeless except that my throat burns when I draw breath... I can scarcely go on. No despair, no happiness, no anxiety. I have not lost the mastery of my feelings, there are actually no more feelings. I consist only of will. After each few metres this too fizzles out in unending tiredness. Then I think nothing. I let myself fall, just lie there. For an indefinite time I remain completely irresolute. Then I make a few steps again.
