"Anyone who has actually been that sad can tell you that there's nothing beautiful or literary or mysterious about depression. 

Depression is like a heaviness that you can't ever escape.  It crushes down on you, making even the smallest things like tying your shoes or chewing on toast seem like a twenty-mile hike uphill.  Depression is a party of you; it's in your bones and your blood.  If I know anything about it, this is what I know: It's impossible to escape."
