At the age of 25, after a "catastrophic" marriage, J.K. Rowling found herself to be a single mother with little money.
"At that point I was definitely clinically depressed," she once told Oprah in a televised interview.
"It's so difficult to describe [depression] to someone who's never been there, because it's not sadness. I know sadness. Sadness is to cry and to feel.
