Infinite Jest

by David Foster Wallace

It’s a kind of emotional novocaine, this form of depression, and while it’s not overtly painful its deadness is disconcerting and… well, depressing. Kate Gompert’s always thought of this anhedonic state as a kind of radical abstracting of everything, a hollowing out of stuff that used to have affective content. Terms the undepressed toss around and take for granted as full and fleshy—happiness, joie de vivre, preference, love—are stripped to their skeletons and reduced to abstract ideas. They have, as it were, denotation but not connotation. The anhedonic can still speak about happiness and meaning et al., but she has become incapable of feeling anything in them, of understanding anything about them, of hoping anything about them, or of believing them to exist as anything more than concepts.

Now THIS description of depression (anhedonia) I can really relate to.
