An individual in despair despairs over something. . . . In despairing over something, he really despair[s] over himself, and now he wants to get rid of himself. Consequently, to despair over something is still not despair proper. . . . To despair over oneself, in despair to will to be rid of oneself-this is the formula for all despair.

I do not care for anything. I do not care to ride, for the exercise is too violent. I do not care to walk, walking is too strenuous. I do not care to lie down, for I should either have to remain lying, and I do not care to do that, or I should have to get up again, and I do not care to do that either. Summa summarum: I do not care at all.
