It's important to remember that online tests are not always accurate or comprehensive assessments of someone's personality. Additionally, self-reporting tests like narcissistic personality tests can be influenced by various factors, including how someone perceives themselves at the moment they take the test.
If the test you took suggests that you have high narcissistic traits, it doesn't necessarily mean that you have a narcissistic personality disorder (NPD). Narcissism exists on a spectrum, and having some narcissistic traits is not uncommon, nor is it necessarily "bad." Everyone has some degree of self-interest and self-concern, which are normal aspects of human behavior.
However, if you are concerned about your self-perceived narcissistic traits or how they might impact your life or relationships, it could be helpful to reflect on your behaviors and attitudes. If you find that these traits are causing distress or negatively affecting your relationships, it might be worthwhile to seek guidance from a mental health professional. They can provide you with a more accurate assessment and help you explore any underlying issues or concerns.
It's worth noting that having self-awareness and a willingness to improve are positive steps towards personal growth. Understanding your own tendencies and behaviors can lead to healthier relationships and a more balanced outlook on life.
