The quote reflects a deep frustration from the speaker, who feels overwhelmed and exploited in a familial situation. It highlights the emotional toll of being constantly tested and treated like an experiment, suggesting a struggle with illness and a lack of understanding from loved ones. This feeling of not being recognized or validated for one's suffering can lead to feelings of isolation and resentment.

In "My Sister's Keeper" by Jodi Picoult, this sentiment captures the essence of the protagonist's challenges and the complexities of family dynamics when faced with chronic illness. The desire for autonomy and recognition is a critical theme, emphasizing the need for compassion and empathy within familial relationships, especially in difficult times.
