Then I start worrying about worrying about worrying about worrying, and suddenly my mind feels so crowded, as if my thoughts aren’t filtering out in the way most thoughts do. As if something is blocking the exit. As if, rather than in and out of my mind in an orderly line, one thought replacing another, they linger. All of them. Half sound like me; they speak with the internal voice I’ve always recognized as my own. The other half do not. The other half—they have their own voice.
