The bottom line is that my life has already almost slipped away from me. I have two choices: I can end it or I can fight like hell to save it.

In the psychological literature, depression is often seen as a defense against sadness. But I'll take sadness any day. There is no contest. Sadness carries identification. You know where it's been and you know where it's headed. Depression carries no papers. It enters your country unannounced and uninvited. Its origins are unknown, but its destination always dead-ends in you.

I'm getting less good at faking it. People in my family are noticing and asking what's wrong. My friends give me invitations to talk, to cry. I love them for their caring, but I want to run from it. I have lost their language, their facility with words that convey feelings. I am in new territory and feel like a foreigner in theirs.

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

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.
