William Styron emphasizes the risks associated with "incomplete mourning," a state where an individual struggles to fully process their grief. This lack of resolution can lead to a buildup of negative emotions such as rage and guilt, creating a heavy burden that the young person carries into adulthood. The failure to experience a cathartic release of sorrow can contribute to deep emotional distress and potential self-destructive tendencies.

In his work "Darkness Visible: A Memoir of Madness," Styron highlights how unresolved grief can manifest in various detrimental ways, making it crucial to address feelings of loss. Such unprocessed emotions can become toxic, leading individuals to struggle with their mental health and overall well-being. Proper mourning and emotional expression are vital for healing and preventing long-term psychological issues.
