Hello Inneedofanewlife: The Skeezyks was also bullied in school for years both verbally & physically.

Everyone, including my parents, knew what was happening. But nobody did anything. At one point, one of the bullies caught me on the school bus & proceeded to beat me up, breaking my nose in the process. I got blamed for it.
I also have never been open about what happened to me.

And, when I was younger, I also masked feelings of inferiority by acting the opposite.

Now that I'm an older person, I simply keep to myself. I no longer want to have anything to do with anyone, if I can avoid it.
The Skeezyks isn't knowledgeable with regard to mental health diagnoses / conditions.

But, from my perspective, I don't think that putting up an air of superiority, in order to mask past abuse, makes one a narcissist.

I think it simply means that you protected yourself in the only way you knew how...
