Is this normal or am i just WAYYY too shy ?!

I would say i am an introvert, dare i say shy. I am very quiet, most of my classmates have never heard me speak. And i do everything in my power to not socialize with anyone, including my family. I am sometimes allowed to stay at home for the day if i do all of my class work on my laptop. And i only go to the stores at night, for whatever i might need.
Is it normal to be this socially distant ? Or should i seek some kind of professional help ?
