"Even if nothing was wrong before the depressive episode, everything seems wrong when it descends. Suddenly, no one seems loving or lovable. Everything is irritating. Work is boring and unbearable.

What was challenging feels overwhelming; what was sad feels unbearable; what felt joyful feels pleasureless—or, at best, a fleeting drop of pleasure in an ocean of pain."
