Hi
I think something to remember is that if a professional thinks it is narcissism at all, the traits are on a continuum, so NPD may not be applicable. The traits however are important to mention with examples as well to paint the picture.
Good thing is that NPD and narcissism near to the actual diagnosis is usually with little or no insight, while you seem to see these patterns in your life.
"Full-blown" narcissists tend to never seek help, as they do not see any reason to improve on anything, or that anything is wrong.
That being said, there are other avenues to explore as reasons for certain behaviors, but more import than that is identifying and working on the behaviors themselves.
