Honestly? I've seen worse. I wonder if you're just a young ENFP with a grandiose idealized self.
You're mildly narcisstic, but I don't about severely --- like I've said, I've seen worse. You seem to be able to admit that you're wrong and have flaws, etc.
I am not convinced that you totally are *not* a narcissist, though, since you believe there's such a thing as "healthy narcissism" and other things you said in the other thread.
That's why I voted mild NPD.
I think you really should talk to a professional, though, honestly. People can think all kinds of things about you on the Internet, bro.
