In Miguel de Cervantes Saavedra's "Don Quixote," the author explores the destructive nature of negative emotions such as disdain, suspicion, jealousy, and fear of oblivion. He suggests that these feelings can lead to the deterioration of relationships and ultimately harm one's sense of wellbeing. Disdain can lead to a lack of care for others, while suspicion may erode trust and patience in relationships. Jealousy can have extreme consequences, reminiscent of violence, reflecting the intensity of these emotions.

Furthermore, the consequences of long absence can cause confusion and turmoil in one's life, highlighting how separation can disrupt personal connections and happiness. The fear of being forgotten or deemed insignificant can overshadow hopes for a fulfilling life. Overall, Cervantes poignantly illustrates how these darker sentiments can hinder joy and satisfaction, emphasizing the importance of emotional health in maintaining a happy existence.
