“One February morning, I woke up to something alarming that had happened overnight – the whites of my eyes had grown larger than my irises, tiny black bubbles swimming in a vast white mass. Imagine if you were walking down a narrow street and came face to face with a big dog. It was the sort of look you would see in its eyes. I stared into the mirror for a moment. I pursed my lips and tilted my head as I tried to think of what might have caused this startling change.”
