That terrible mood of depression of whether it's any good or not is what is known as The Artist's Reward.

Biographer and critic Leon Edel observed, in a 1988 interview, "The greatest enemy of writers is depression, which they can't avoid.")
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), U.S. feminist theorist, literary critic, essayist, autobiographer, sculptor. The Loony-Bin Trip, pt. 3, Simon and Schuster (1990).)
In the larger view the major forces of the depression now lie outside of the United States, and our recuperation has been retarded by the unwarranted degree of fear and apprehension created by these outside forces.
