"The natural state of the sentient adult is a qualified unhappiness. I think also that in an adult the desire to be finer in grain than you are only adds to this unhappiness in the end" - F. Scott Fitzgerald, as quoted in Nonconformity by Nelson Algren.
Of course all life is a process of breaking down, but the blows that do the dramatic side of the work -- the big sudden blows that come, or seem to come, from outside -- the ones you remember and blame things on and, in moments of weakness, tell your friends about, don't show their effect all at once. There is another sort of blow that comes from within -- that you don't feel until it's too late to do anything about it, until you realize with finality that in some regard you will never be as good a man again.
"Instead of being so sorry for yourself, listen -- “she said. (She always says “Listen,” because she thinks while she talks -- really thinks.) So she said: “Listen. Suppose this wasn’t a crack in you -- suppose it was a crack in the Grand Canyon.”
“The crack’s in me,” I said heroically.
“Listen! The world only exists in your eyes -- your conception of it. You can make it as big or as small as you want to. And you’re trying to be a little puny individual. By God, if I ever cracked, I’d try to make the world crack with me. Listen! The world only exists through your apprehension of it, and so it’s much better to say that it’s not you that’s cracked -- it’s the Grand Canyon.”
Now the standard cure for one who is sunk is to consider those in actual destitution or physical suffering -- this is an all-weather beatitude for gloom in general and fairly salutary daytime advice for everyone. But at three o’clock in the morning, a forgotten package has the same tragic importance as a death sentence, and the cure doesn’t work -- and in a real dark night of the soul it is always three o’clock in the morning, day after day. At that hour the tendency is to refuse to face things as long as possible by retiring into an infantile dream -- but one is continually startled out of this by various contacts with the world. One meets these occasions as quickly and carelessly as possible and retires once more back into the dream, hoping that things will adjust themselves by some great material or spiritual bonanza. But as the withdrawal persists there is less and less chance of the bonanza -- one is not waiting for the fade-out of a single sorrow, but rather being an unwilling witness of an execution, the disintegration of one’s own personality…
Unless madness or drugs or drink come into it, this phase comes to a dead end, eventually, and is succeeded by a vacuous quiet. In this you can try to estimate what has been sheared away and what is left.
Trouble has no necessary connection with discouragement -- discouragement has a germ of its own, as different from trouble as arthritis is different from a stiff joint.
