What a label cannot tell you
A diagnosis cannot be inferred from a listicle, a social-media clip or one relationship story. NPD is a professional clinical assessment, and people with the same diagnosis are not interchangeable. Nor does a diagnosis excuse harmful conduct. It is reasonable to set a boundary around a behavior without deciding what condition, if any, explains it.
If a pattern is affecting your wellbeing, focus on the specific events, your needs and support available to you. Avoid using “narcissist” as a slur; precise language supports safer conversations and avoids stigma toward people who have a mental-health condition.
