Little has been written regarding the experience of training in medicine with a diagnosis of a personality disorder. The stigma of personality disorders, evidenced even within psychiatry, potentially marginalises affected students and resident doctors. This article provides a first-hand account of the lead author’s (E.M.) lived experience of being a medical student with a diagnosis of emotionally unstable personality disorder (EUPD). Challenges that have been faced include a lack of understanding, limited literature about medical students and doctors with personality disorders, and derogatory attitudes. Despite this, the positive aspects of the diagnosis are recognised, through enhanced resilience and heightened emotional sensitivity, which can benefit patients.
