Doubts on being a "covert" narcissist

I apologize in advance for possible grammar mistakes. Today one of my therapists (a psychologist) suggested that I could be a "covert" narcissist, or at least that I could have some traits of that disorder. Honestly it was the first time I heard of this word, "covert", although I knew the word "narcissist", so I was a bit confused and after the meeting I started searching online for clarification. Long story short, the two important things for me are: I'm very competitive intellectually by nature and I was bullied at high school. Also, it's important to mention that in high school I was very bad in Maths but, when we started Calculus, I became interested in it and started studying it, also for social "revenge" and "glorification". That led to me starting a Maths degree like three years ago, of which I completed with average results a little more than one year of study before entering therapy for what I suppose was depression (I studied too much alone, did not follow lectures and tried to avoid social life in general). After that, I changed like three or four degrees because of confusion and anger for what I felt was not right. Now I recovered, and I'm back into Maths in some way. Despite that, I'm still focused on what happened in that strange period and in high school, which I consider an unforgettable failure in my life both academically and socially. Although I have few "real" friends (3,4), I'm now active socially in a group of people without any problems. After this data, I ask about what should I do about these words of being a "covert" narcissist: should I, for example, ask for clarifications directly to my therapist or should I simply "trust" him/her, work about it at therapy with the chosen path and forgetting the curiosity of the possible "level" of the disturb ?

How will you apply your math degree to your covert revenge scheme?

Now I'm pursuing an Engineering degree as I've found sone peace with an hobby. My scheme was very simple: as an intellectually superior individual I would be justified and able to damage my "opponents" with violence. That would be preceded by a necessary intellectual damage, the degree by itself or something more involved.

To answer your question, Id stay open to therapy but keep in mind most all young adults have many narcissistic tendencies. Your scheme is interesting, albeit vague - whatever helps you sleep better at night.
