Pain split my forehead in two. The upper region—the part I was sure was responsible for planning, judgment, decision making, knowing right from wrong—felt like it was wrapped in a two pound bag of hot potatoes. Behind that cranial layer of pressure-cooker mush, hundreds of tiny splinters were being hammered into my eye sockets, deadening my ability to see and move. Nothing, I was convinced, was going to save me from this pain, except perhaps a lobotomy.
