I know this is silly, but I was just wondering if it's normal to be extremely introverted. I used to be very outgoing my freshman year, but something happened when I moved sophomore year that made me this way. Now that I'm a junior I'm back at my old school, but I have a lot less friends because I'm more withdrawn and I seem to not know how to act towards people. I still have friends, it's just that I guess I'm more selective. Thoughts?
