"DON'T KNOW WHO I AM," RICH SAYS OVER AND over. "There are too many thoughts inside my head. I am not myself." Yesterday he said, "Pretend you are walking up the street with your friend. You are looking in windows. But right behind you is a man with a huge roller filled with white paint and he is painting over everywhere you've been, erasing everything. He erases your friend. You don't even remember his name." The image makes me shiver, but he seems exultant in his description. There are days when he is grounded in the here and now and days when his brain is boiling over with confusion."
