In the book "Chalice" by Robin McKinley, the protagonist grapples with feelings of despair but recognizes that succumbing to such emotions would be detrimental. She understands that expressing vulnerability could weaken her position and hinder her responsibilities. Instead of allowing despair to consume her, she strives to remain strong and focused in the face of challenges.

The quote, "Despair was a private weakness she could not afford to indulge," highlights the internal struggle the character faces. It emphasizes the importance of resilience and the necessity to confront difficulties with strength rather than giving in to the temptation of hopelessness. This mindset is crucial for her to fulfill her role and protect those who depend on her.
