Understanding the Disease
What Is Borderline Personality Disorder — and Why Does It Often Co-Occur with Addiction?
Borderline Personality Disorder (BPD) is a serious mental health condition characterized by pervasive instability in emotions, self-image, and interpersonal relationships. The National Institute of Mental Health describes it as a pattern of problematic thinking, feeling, and behavior that disrupts family and work life, long-term planning, and sense of self-identity.
People with BPD often experience intense emotional pain, a deep fear of abandonment, unstable relationships marked by idealization and devaluation, chronic feelings of emptiness, and impulsive self-destructive behaviors — including substance abuse. Because the emotional dysregulation is so intense and so persistent, substances often become the only available coping mechanism.
At Northbound, our clinicians are trained to treat BPD and addiction simultaneously using evidence-based modalities, particularly Dialectical Behavior Therapy (DBT) — one of the most effective treatments available for borderline personality disorder. We also respect each client's right to dispute a diagnosis; our focus is on helping people, not labeling them.

Recognizing the Problem
Signs of Borderline Personality Disorder Addiction
BPD is frequently misdiagnosed or missed when substance use is present. These signs — in yourself or someone you love — indicate a need for professional dual diagnosis assessment.
