three o’clock in the morning

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 every one. But at three o’clock in the morning … 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.

F. Scott Fitzgerald
