In "Darkness Visible: A Memoir of Madness," William Styron reflects on the profound effects of mental illness on the individual experience. He highlights how, in times of severe distress, various aspects of life, including sexuality, can diminish. This loss of libido is emblematic of the overwhelming nature of mental health crises, suggesting that the body's basic desires become secondary in the face of significant psychological challenges.

Styron's poignant observation underscores the idea that while libido is typically a vital component of human life, it can suddenly feel extraneous when a person is grappling with dire circumstances. This shift illustrates the body's instinctive priorities during times of crisis, where survival and coping take precedence over more intricate emotional needs.
