I don't think immediate tragedy is a very good source of art. It can be, but too often it's raw and painful and un-dealt-with. Sometimes art can be a really good escape from the intolerable, and a good place to go when things are bad, but that doesn't mean you have to write directly about the bad thing; sometimes you need to let time pass, and allow the thing that hurts to get covered with layers, and then you take it out, like a pearl, and you make art out of it.
