One morning I would wake into an intense, almost electric energy, filled with good humour and possibility. It would last for a few days, during which I became euphoric and voluble—sometimes, alarmingly so—and then, just as suddenly, it would be gone. Somehow, that was worse. The contrast between the light and the dark felt almost unbearably sharp, and the dark a colder, bleaker place than I remembered when I spent all my time encased in it.
