Mauerbauertraurigkeit :

The inexplicable urge to push people away, even close friends who you really like—as if all your social tastebuds suddenly went numb, leaving you unable to distinguish cheap politeness from the taste of genuine affection, unable to recognize its rich and ambiguous flavors, its long and delicate maturation, or the simple fact that each tasting is double-blind.

Sonder :

the realization that each random passerby is living a life as vivid and complex as your own.

Enoument :

The bitter-sweetness of arriving at the future, seeing how things turned out, but not being able to tell your past self.

Mal de Coucou :

n. a phenomenon in which you have an active social life but very few close friends—people who you can trust, who you can be yourself with

Kairosclerosis :

n. the moment you realize that you’re currently happy—consciously trying to savor the feeling—which prompts your intellect to identify it, pick it apart and put it in context, where it will slowly dissolve until it’s little more than an aftertaste.

Jouska :

n. a hypothetical conversation that you compulsively play out in your head—a crisp analysis, a cathartic dialogue, a devastating comeback—which serves as a kind of psychological batting cage where you can connect more deeply with people than in the small ball of everyday life, which is a frustratingly cautious game of change-up pitches, sacrifice bunts, and intentional walks.
