What's interesting is that apparently no one is safe from depression. Here is Phelps, an accomplished man by any means, saying he was thinking of suicide.

I always think "if I do this, if I do that, it will all get better". It does, for a while. I've changed my surroundings and life several times, used all the drugs, but depression always comes back. You have to just learn to live with it. Weird stuff.
