I have much identification with this quote and there was a time, I lived it practically everyday. Today I understand it quite well.
"Blues like this lives out of sight of the world, I think. It seems more of a solid organic mass than a mood that can blow away or be lifted. It lies there and says, Go ahead, try to budge me. ... Blues like this doesn’t have ears. It can’t be disturbed. It has nothing to do with sadness or even grief—which at least are imaginable emotions." –Michael Greenberg, Hurry Down Sunshine
