Borderline Personality Disorder (BPD) and Narcissistic Personality Disorder (NPD) are two personality disorders you wouldn’t necessarily associate with each other. But because the two disorders share the same “B cluster” grouping in the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) – including erratic, dramatic, and emotional behaviors – they may be confused.

Because individuals with BPD exhibit instability in many areas of their lives, it is often difficult to diagnose the disorder, especially since BPD symptoms can mimic those of other disorders (such as Bipolar Disorder). While this potential confusion between disorders may delay the diagnosis of BPD, the importance of accurately identifying the underlying psychiatric issues supersedes any inclination to reach a diagnosis quickly.

While family and loved ones generally feel compassion and desire recovery and lasting mental well-being for the person in their lives with Borderline Personality Disorder, the disorder can also cause great stress in your own life. Being in the presence of someone whose world is a rollercoaster of emotions can be taxing. In order to cope with the presence of a person with BPD in your life, it is important to figure out what you need to do to deal with what you’re feeling and how you react.
