In Cecelia Ahern's book "P.S. I Love You," the quote "You gotta be rich to be insane, Hol. Losing your mind is not a luxury for the middle class" highlights the notion that mental health struggles often come with societal and economic implications. The author implies that wealth provides a buffer that allows some individuals to express or explore their mental health issues more openly, while those in lower socioeconomic classes may lack the resources and support to cope or seek help.
This commentary can be perceived as a reflection on the disparities in mental health treatment and societal perceptions based on class. It suggests that the burden of mental health issues may be heavier for those without financial resources, who might fear the repercussions of being unable to manage their mental health openly. Ahern's message draws attention to how socioeconomic status can influence one’s experience of mental health and the societal expectations surrounding it.
