I know how you feel. I love my concentration and fascination with all sorts of different things. I absolutely hate seeing all sorts of "different" people and realizing that they're all the same. I just recently stopped talking to my best friend, and someone I had really come to love, because they criticized my personality in a way that made me understand how little they actually knew of me. Now I think all the times he was acting "dull" wasn't just joking around, and I think he actually has some deep seated prejudice against me because of my "intelligence"...
To everyone saying this is an age problem: I've felt like this since I was in preschool. It feels even worse now, like (for the NT's) looking around you and seeing that everyone is successful, has a car, a wife, a nice house, and all that other BS. Well, I look around and see how much of the world everyone is able to ignore. It feels worse because I'm at the age (18) where I'm being forced into the world, and it's not so much a bad thin that I'll be independent soon, it's not that at all. It's that I'm coming in contact with more people and expanding my "horizons", just to find out that it's the same all around.
To OP: I'm sorry if this is depressing. I live in a different city than you, have a different home life, different exposure, everything. Our situations aren't and can't ever be the same, so hopefully (and most likely) you'll have better luck than I. You are quite young, so use what time and energy you want to find whatever makes you happy.
