Diane Arbus, barbiturate + slashing the wrist, you're never too sure.
I really resonate with her words: "I go up and down a lot. Maybe I've always been like that. Partly what happens though is I get filled with energy and joy and I begin lots of things or think about what I want to do and get all breathless with excitement and then quite suddenly either through tiredness or a disappointment or something more mysterious the energy vanishes, leaving me harassed, swamped, distraught, frightened by the very things I thought I was so eager for! I'm sure this is quite classic."
And that quote from Joel Meyerowitz: "If she was doing the kind of work she was doing and photography wasn't enough to keep her alive, what hope did we have?"
This is pretty much where I'm at, as a former artist who lost his spark.
