I've been diagnosed with narcissistic pd, why is it a big deal? is there something wrong with it?

It can be a big deal: I do not know the specifics of your situation, but it can cause depression and anxiety, behavior tat is toxic to others, and a failure to empathize with others that leads to unhappiness in those close to you. There is often a failure to prioritize, with the narcissist placing job and money above family. It can alienate people from you. Please get therapy as it can be helped.Empathy is key to tx.

Narcissism: Typically narcissists come to treatment after driving away anyone close to hem, alienating bosses, coworkers, objectifying people in general, not being able to empathize with others, and in general not being able to own their own part in their own misery. Psychoanalysis is the most powerful therapeutic tool for this.
