If you know someone who's depressed please never resolve to ask them why. Depression isn't a straightforward response to a bad situation, depression just is, like the weather.
Try to understand the blackness, lethargy, hopelessness and loneliness they're going through. Be there for them when they come through the otherside. It's hard to be a friend to someone who's depressed, but it is one of the kindest, noblest and best things you will ever do.
