I like how JJ goes on a long angry rant against Illini and then he's all calm in his replies in this thread like nothing happened.
Narcissistic Personality Disorder (NPD) is a mental health condition characterized by an inflated sense of self-importance, a deep need for excessive attention and admiration, troubled relationships, and a lack of empathy for others, often masking a fragile self-esteem that's highly sensitive to criticism. Symptoms include entitlement, fantasies of success, exploiting others, and arrogance, with distinct grandiose (overtly arrogant) and vulnerable (hypersensitive, shame-filled) subtypes. While causes are complex, involving genetics and environment, treatment focuses on psychotherapy (like CBT) to manage behaviors and improve functioning, though people with NPD rarely seek help for the disorder itself.
