There's is a time honored mythology of the neurotic artist who creatively feeds off his or her own trauma –that creativity is a function of inner friction. I've never fully subscribed to that.

You don't need to create personal trauma to experience darkness, In fact, in some rarefied theological schools of thought, one could argue the opposite.
