If you're trying to identify if you have encountered a narcissist, keep in mind that narcissistic personality disorder is a specific and serious diagnosis that should be made by a mental health professional. Traits associated with narcissism can include a lack of empathy for others, an inflated sense of importance or entitlement, a constant need for admiration, and often a disregard for others' feelings. However, having some of these traits does not necessarily mean that someone has narcissistic personality disorder.
If you believe you're in a relationship with a narcissist and it's causing you distress, consider seeking support from a mental health professional. They can provide guidance on how to navigate the situation and ensure your wellbeing.
