Don't worry about your little one. She is definitely confused but I don't think that's why she is pulling tricks on her teacher. My kids were like that when they were 2-3 and we were fine back then They go through stages and phases. Just be consistent and make her feel secure.
As far as you is concerned, maybe taking baby steps "out there" would be a good idea. Once you figure out you enjoy things you didn't think you would, it will be so much easier to "expand". BTW, you would be the last person I would call antisocial on this board... You come across as exactly the opposite...
