This paper employs narratology to explore the portrayal of Borderline Personality Disorder (BPD) in Connie Palmen's Your Story, My Story. Focused on emotional volatility and identity conflicts, the study investigates the novel's contribution to the broader discourse on mental health in literature. Key questions guide the analysis, examining narrative techniques' alignment with BPD experiences, the novel's impact on prevailing literary portrayals, and its role in enhancing understanding of character dynamics. The research contends that Palmen's novel captures literary reflections of BPD, challenging traditional clinical interpretations.   The examination, rooted in narratology, reveals how storytelling mechanics mirror BPD's multifaceted nature. Extending beyond Palmen's work, the study emphasizes an interdisciplinary approach, combining psychological theories with literary analysis. It concludes that narratology serves as an indispensable tool in literary psychology, shaping and reflecting psychological realities. Your Story, My Story stands as a testament to literature's power in portraying complex mental health issues, urging future research at the psychology-literary studies intersection. The paper suggests continued exploration into how literature contributes responsibly to the mental health discourse, encouraging studies on the intersection of literary art and psychological realism.
