This summer, I returned to my home in Delhi to learn that my father's cousin, Sarita, had committed suicide. She and I were not terribly close; I hadn't seen her in years. Yet the funeral was one of the more influential occasions of my life. I couldn't stop thinking: What could drive a vibrant, intelligent and successful young woman to take her own life? What was missing? What went wrong? I grew to realize that this was not a singular event.
