I did bullied my ex boyfriend's sister in the past but is it bad that I don't feel remorse for it?

We were in HS back then (we're now 26 year-old women) and when she kept confronting me with the past in private a couple times, I refused to acknowlegment. In my mind, I still believe it wasn't as bad as she's making it out to be. I'll give it a 3/10 in rating but to her it's like an 8-9/10. Honestly, I can't feel nor understand her pain at all. I don't understand it.

That issue is concerning me and I'll have my 1st session with a psychologist next week. I already set up the appointment. I think I might have traits of a narcissist (though since I'm recognizing it here, then I might not be a full blown narcissist, maybe partially) and have limited ability to feel remorse or empathy. Is it bad I feel no remorse for it at all?
