Do I need a social life?

Hi, I am a 19 year old med student. I've been bullied in my early school life then closed myself off to people and lost all of my social skills. My parents and people online tell me I need some social life and humans are social animals and I need friends. How true is that? I don't mind being a loner at all. Most people seem "fake" and superficial to me and when I observe most relationships around me they don't seem that interesting, so I don't get the appeal. Also even if I changed my view on this and wanted to make friends, I don't know how I can do that as I've lost all of my social skills.

Thank u for reading
