Scenario: Vee is a 26-year-old African-American woman presenting with a history of non-suicidal self-injury (NSSI), specifically cutting her arms and legs, which she has engaged in since her teenage years. She has also made two suicide attempts by overdosing on prescribed medications—once during adolescence and once six months prior. She reports persistent suicidal ideation, which she considers a source of relief, viewing it as a potential escape from her distress. Vee describes episodes where she "zones out," particularly during stressful situations or conversations, indicating possible dissociative symptoms or emotional regulation difficulties. Additionally, she expresses an ongoing struggle with identity, stating, “I don’t know who Vee really is,” and reports frequently changing her hobbies, clothing style, and even her employment based on her social environment, suggesting identity disturbance.

Vee’s interpersonal relationships fluctuate dramatically; she describes her current partner as both “the best thing” and unbearable at different times. Her impulsivity manifests in spending lavish gifts on him, yet she can also lash out violently, experiencing regret and panic afterward. Her sexual behaviors are marked by episodes of promiscuity involving multiple casual partners prior to her current relationship, indicating possible reckless or impulsive tendencies. These behaviors and her emotional instability are consistent with several potential diagnoses.

Primary diagnosis and differential diagnosis

Based on her presentation, the primary diagnosis appears to be Borderline Personality Disorder (BPD), coded as 301.83 (DSM-5) and F60.3 (ICD-10). Vee exhibits pervasive patterns of unstable interpersonal relationships, markedly fluctuating self-image, impulsivity, intense fear of abandonment, recurrent suicidal behaviors, and non-suicidal self-injury—all characteristic features of BPD. Her emotional dysregulation, identity disturbance, and episodes of dissociation further support this diagnosis.

Differential diagnoses include Bipolar Disorder (particularly BPD with mood swings), Major Depressive Disorder (considering her suicidal ideation), and Post-Traumatic Stress Disorder (due to possible trauma history). Bipolar disorder can present with mood swings similar to those in BPD, but her rapid, intense fluctuations and interpersonal instability emphasize BPD as more prominent. MDD would primarily focus on persistent depressive episodes, which are not explicitly described here, although her suicidal ideation warrants consideration. PTSD might be relevant if trauma history is confirmed, but her core clinical features align more closely with BPD thresholds.

Cluster classification

The primary diagnosis, Borderline Personality Disorder, belongs to Cluster B of the DSM-5 personality disorders. Cluster B is characterized by dramatic, emotional, or erratic behaviors, including features such as emotional instability, impulsivity, and intense interpersonal relationships.

Formulation and prioritized treatment plan

Formulating Vee’s case involves recognizing the constellation of emotional dysregulation, impulsivity, identity disturbance, and chronic suicidality as core components of her Borderline Personality Disorder. Her history of NSSI, impulsive spending, and volatile relationships reinforce this diagnosis. Interpersonal difficulties, such as fluctuating feelings towards her partner, reflect intensity and instability typical of BPD. Additionally, her dissociative episodes and sense of emptiness are important considerations.

The treatment plan should prioritize establishing safety and reducing harmful behaviors. Dialectical Behavior Therapy (DBT) is evidence-based and effective in managing BPD, particularly targeting self-injury, emotional regulation, and distress tolerance (Linehan, 2018). Psychoeducation about her condition and trauma-informed approaches are also essential. Medication can be used adjunctively, focusing on comorbid symptoms such as depression or anxiety, but it is not foundational. Establishing a strong therapeutic alliance, regular monitoring of suicidality, and developing coping skills are critical early objectives.

Long-term goals include improving emotional stability, reducing impulsive and self-destructive behaviors, enhancing her self-identity, and fostering healthier interpersonal relationships. Addressing underlying trauma and possible dissociative symptoms should be integrated into therapy, potentially with modalities such as schema-focused therapy or mentalization-based treatment. Coordination with a multidisciplinary team ensures comprehensive care, including social work resources for housing, employment, and social support systems.
