Bitter Grounds

Bitter Grounds is a 2003 Neil Gaiman short story. You can read it online here. It begins,

In every way that counted, I was dead. Inside somewhere maybe I was screaming and weeping and howling like an animal, but that was another person deep inside, another person who had no access to the face and lips and mouth and head, so on the surface I just shrugged and smiled and kept moving. If I could have physically passed away, just let it all go, like that, without doing anything, stepped out of life as easily as walking through a door, I would have done. But I was going to sleep at night and waking in the morning, disappointed to be there and resigned to existence.
