If you stay awake late enough, eventually you remember everything. All your usual defenses dissolve. Your mind is weary, and there is nothing in your white, silent room to distract it. Your exhausted brain can no longer apply the pressure needed to repress your memories, and they all come back, all of them, every one, and especially the ones that prove you are the worst version of yourself: the lies, the evasions, the unreturned emails, the shoplifted packs of gum. And, of course, every single ungenerous thing you have ever thought, no matter how fleetingly or how long ago, about the people you love most. Anxiety cascades: just when you’ve drained one disaster from your mind, another breaks the dam. The panic and shame that overcome you when you find a really old to-do list and realize you haven’t done a single item on it? Multiply that feeling by the number of minutes left until sunrise. You can tell yourself to be reasonable, to count your blessings, to get it together, but such reassurances will ring hollow. As Fitzgerald put it, at three o’clock in the morning a forgotten package feels as tragic as a death sentence.
