Famous quotes containing the word depression:
“During depression the world disappears. Language itself. One has nothing to say. Nothing. No small talk, no anecdotes. Nothing can be risked on the board of talk. Because the inner voice is so urgent in its own discourse: How shall I live? How shall I manage the future? Why should I go on?”
—Kate Millett (b. 1934)
