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 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.

Depression is such a cruel punishment. There are no fevers, no rashes, no blood tests to send people scurrying in concern. Just the slow erosion of the self, as insidious as any cancer. And, like cancer, it is essentially a solitary experience. A room in hell with only your name on the door.

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

Some struggles are so solitary that they drown in words.

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.
