Hi! I was considered a "shy" child, too. It was only when I got into therapy that I found out why I was having trouble relating to people, so you might find it helpful to talk to a school counselor or a therapist.

Just from what you have said, I can't really grasp what might be happening with you. Of course, since we aren't professionals, then we aren't able to diagnose, anyway.

Might it be possible that you have something such as Asperger's? That diagnosis comes to my mind because I just read a book called Look Me in the Eyes by Robison, who learned he had it when he was 40 years old.
