Regarding the Narcissistic Personality Disorder test you took, a score of 18 out of 40 indicates that you have a relatively low likelihood of exhibiting traits associated with narcissistic personality disorder. However, it's essential to remember that online tests should not be used as definitive diagnoses. If you have concerns about your personality or mental health, it's best to consult a mental health professional for a comprehensive evaluation and guidance.
Keep in mind that personality traits exist on a spectrum, and occasional self-reflection and introspection can be beneficial for personal growth and self-awareness. It's also helpful to remember that seeking professional support and guidance can be valuable in understanding oneself better and addressing any challenges or concerns you may have.
