People tell that i'm a narcissist, is it that bad to be a narcissist?

They tell that i sometimes can be very manipulative, i always brag about myself, i'm selfish and not easy-going at all. I think that i'm confident not narcissist. they insist on telling me that i'm narcissist. but i don't think so. People are trying to bring me down because i'm confident and i get more attention from people than they do. i assume that's why they are always trying to bring me down by spreading bad vibes with their words.
