[...] A very glib guy on the television said some people liken it to being underwater, under a body of water that has no surface, at least for you, so that no matter what direction you go, there will only be more water, no fresh air and freedom of movement, just restriction and suffocation, and no light. (I don't know how apt It is to say it's like being underwater, but maybe imagine the moment in which you realize, at which It hits you that there is no surface for you, that you're just going to drown in there no matter which way you swim; imagine how you'd feel at that exact moment, like Descartes at the start of his second thing, then imagine that feeling in all its really delightful choking intensity spread out over hours, days, months ... that would maybe be more apt.)

The so-called 'psychotically depressed' person who tries to kill herself doesn't do so out of quote 'hopelessness' or any abstract conviction that life's assets and debits do not square. And surely not because death seems suddenly appealing. The person in whom Its invisible agony reaches a certain unendurable level will kill herself the same way a trapped person will eventually jump from the window of a burning high-rise. Make no mistake about people who leap from burning windows. Their terror of falling from a great height is still just as great as it would be for you or me standing speculatively at the same window just checking out the view; i.e. the fear of falling remains a constant. The variable here is the other terror, the fire's flames: when the flames get close enough, falling to death becomes the slightly less terrible of two terrors. It's not desiring the fall; it's terror of the flames. And yet nobody down on the sidewalk, looking up and yelling 'Don't!' and 'Hang on!', can understand the jump. Not really. You'd have to have personally been trapped and felt flames to really understand a terror way beyond falling.
