6: My Life Is a Roller Coaster: The Subjective Experience of Borderline Personality Disorder

This chapter delves into the lived accounts of individuals diagnosed with borderline personality disorder (BPD), employing Interpretative Phenomenological Analysis (IPA) to uncover the intricate layers of their inner worlds. Drawing from in-depth interviews with ten participants, the chapter explores how individuals grapple with shifting moods, relational turmoil, and a pervasive sense of fragmentation. Rather than offering a purely diagnostic overview, it emphasizes personal narratives as rich sources of insight into the challenges and paradoxes of navigating everyday life with BPD. The chapter identifies key experiential domains, such as cognitive patterns, affective responses, interpersonal dynamics, and coping behaviors, while also analyzing how participants respond to their diagnoses and interactions with mental health systems. Special attention is given to the theme of emotional volatility, selected for further investigation through microphenomenological interviewing, highlighting the potential for nuanced and embodied access to emotional experience. The findings not only shed light on subjective suffering but also point toward strategies of adaptation, meaning-making, and resilience, offering a valuable contribution to clinical understanding and qualitative inquiry into complex emotional conditions.
