The quote illustrates the feelings of neglect and emotional turmoil experienced by the speaker, who seems to feel undervalued and overlooked by their family. The sentiment suggests that their existence is deemed significant only when they are needed for medical purposes, highlighting a transactional relationship rather than a nurturing one. This speaks to a deeper issue of familial dynamics, especially in situations where one member's health profoundly impacts the resources and attention afforded to others.

The reference to Kate being sick serves as a poignant reminder of the complexities in relationships shaped by illness. It unveils the struggle of the speaker, who grapples with being reduced to merely a source of help for a sibling's health challenges. This dynamic raises questions about identity, autonomy, and the emotional costs of living in the shadow of another's suffering, themes explored throughout Jodi Picoult's "My Sister's Keeper." The narrator's voice reveals a profound sense of isolation amidst their familial obligations.
