At its core, loneliness is a complex emotional state that arises from a perceived discrepancy between an individual's desired and actual social relationships. For sisters, or more broadly, women, societal expectations often exacerbate feelings of isolation. They are frequently encouraged to be nurturing, to prioritize others' needs over their own, and to embody a stoic resilience in the face of personal hardship. These roles can sometimes hinder their ability to express their desires and needs openly, leading to a silent suffering that can be particularly profound.
