Depression in the clinical sense is a really hard thing for people to empathize with. There’s this bootstraps approach, like, “Why don’t you get out of bed and get a job! It’s all up to you.” But that isn’t for everyone. There is a time when you realize: “Whoa, you’re sick just as if your leg was rotting off.” David Foster Wallace is a hero of mine, and I read an interview with his wife where she said that everyone was shocked when he killed himself, but if he had pancreatic cancer, no one would have been shocked. The guy was not well.

I know a lot of people that have been afflicted by anxiety and debilitating depression. It takes this momentum: If you’re not pushing the boulder up the hill, it’s rolling down on you.
