Just stumbled upon this website the other day (it was actually on a facebook ad!).  It is really fascinating.  Even reading about the website and its founder was really interesting.

I already posted a note on facebook about an article on depression in creative people that absolutely spoke to me.  It makes sense that we as creative individuals seek, more than most people, to create and find meaning in life.  When we can't find that meaning, it really gets to us.  I really want to read the author's book, The Van Gogh Blues:  A Creative Person's Path Through Depression.
