It is quite possible for narcissists to recognize that they have such a personality disorder, as HT has demonstrated. (Hat tip to HT!)

It’s important to ask why a narcissist wants to change, though. They could seek change for narcissistic reasons such as they don’t like the label, want others to like them more, or want to feel better about themselves. A non-narcissistic reason could be that they want to stop hurting others, regardless of how such a change affects their own feelings or others’ perceptions (real or imagined) of them.

It’s complicated.

Good luck!
