The images are visual, auditory, olfactory, kinesthetic. They aren't laid down on the same tracks as thought. And sometimes, when they return to you, it is as if you feel them for the very first time. Memory lives on in the details, like the color of a room, a tone of a voice, the touch of a child, the smell of a man.

In these flashes of insight, I understand for a moment that one of the great dividends of darkness is an increased sensitivity to the light.

It's enough just to speak when spoken to, to give some minimal reaction to a stimulus. But to actually be the stimulus doesn't even occur to me.

People say, "I have heart disease," not "I am heart disease." Somehow the presumption of a person's individuality is not compromised by those diagnostic labels. All the labels tell us is that the person has a specific challenge with which he or she struggles in a highly diverse life. But call someone "a schizophrenic" or "a borderline" and the shorthand has a way of closing the chapter on the person. It reduces a multifaceted human being to a diagnosis and lulls us into a false sense that those words tell us who the person is, rather than only telling us how the person suffers.

The infinity of this vacancy, the pervasive pain, the longing for some spirit, some lightness, some joy - that's all that is left.

I would never kill myself intentionally. I couldn't do that to my family, my friends ... But to have fate step in and give me a shove, that's a different matter. Then I have the exit, without the guilt. I am ashamed of myself for thinking like this. But more than anything, I am frightened that it makes me feel so much better to think about it. Sometimes it eases the terror, the sense that I am condemned eternally to this hell.

I should come with a consumer warning, like the labels that say "Handle with care" or "May be hazardous to your health." I am unfit for human consumption. I struggle to articulate how awful and isolating this feels, but I can't find the words.
