Are any of you extremely introverted?

I know we are generally an introverted type, but I am very introverted. I genuinely don't seem to have much of a need or a want for much social contact. I am so happy on my own. I am kind of wondering if this is dysfunctional.

I have had very negative experiences with other people. Sometimes I wonder if I was always like this or that I have become like this. I at least have the security that I won't upset myself. It doesn't help that people constantly shame me for my introversion, makes me want to be even more of a loner. I had some rando insult me and assume sh. about me, because I posted on the introvert sub. They were a teacher and put themselves above me, because "social skills are very important and I clearly didn't have them." I can talk to people just fine, I just don't like it all the time.
