In William Styron's "Darkness Visible: A Memoir of Madness," the author explores the nature of depression, contrasting it with violence. He describes depression as a tumultuous internal struggle but not one characterized by outward aggression. Instead, it manifests as a profound lethargy and emotional numbness, resembling a storm filled with darkness rather than chaos.

This mental state leads to a significant decline in energy and motivation, where individuals often feel paralyzed and drained. Styron emphasizes how deeply depression can affect both the mind and body, leaving one feeling utterly exhausted and without vitality.
