I've been the odd one out at almost every job I've ever had. Don't let it get you down. You're there to earn money, not be bosom buddies. I'd look around for a nice, kind person you can be friends with (who also keeps to themselves) and just maintain a cool distance from everyone else. No need to try to pretend to be anything NT-like because, as one poster said, that just gives them more power over you. In fact, I would be even more inscrutable, keep others a little bit on edge. It will make them respect you more.
Do you work in a corporate job? People can be quite aloof in that sector. Don't take it to heart - it's probably more about the job they're doing than anything you've done.
