Depression, in Karla's experience, was a dull, inert thing - a toad that squatted wetly on your head until it finally gathered the energy to slither off. The unhappiness she had been living with for the last ten days was a quite different creature. It was frantic and aggressive. It had fists and fangs and hobnailed boots. It didn't sit, it assailed. It hurt her. In the mornings, it slapped her so hard in the face that she reeled as she walked to the bathroom.
