Within hours of my best friend’s death this summer, I had faced an onslaught of emotions so intolerable, I felt like a foreigner in my own mind. Grasping for some semblance of order, I began naming my different moods. Example: “A Zombie Just Ate My Body,” which is like being frostbitten and stun-gunned and about 94 percent dead inside. At least that one is bearable, unlike “Get That Serrated Knife Out of My Chest,” which is as painful as it sounds.
