Actually he deliberately avoids calling it depression, granted what he describes sounds a lot like depression.

>"Glover, 30, says he has been feeling down of late – though he shies away from describing his current state as depressed. 'If I’m depressed, everybody’s depressed,' he says. 'I don’t think those feelings are that different from what everybody’s feeling. Most people just don’t tell everybody.'"

In any case, I have a hard time with the idea that we should dismiss somebody's critique of the world because they're upset about the world.
