None of it made any difference. The hollow feeling refused to go away. The next days were very hard. I found myself in the grip of a crippling ennui. I was back at square one, but I couldn’t bring myself to resume my job hunt; it was all I could do to drag myself from the bedroom floor to the sofa. With every passing day my financial affairs grew more ruinous, and it became harder and harder even to conceive of how I might dig myself out of the hole I was in—which only compounded my ennui, and my disinclination to do anything about it.
