I'm pretty much exactly like you. I have some close friends I usually hang out with during free periods, but there's no-one I talk to outside of school hours, nor do I even seek to do so. I don't have relationships either, even though I have experienced what could be judged as 'feelings' a couple of years ago for one person in my year I'm not close friends with. I'm personally waiting until university to find a proper group of friends and a potential 'romantic interest', so-to-speak, as there, I'll meet more like-minded people (and by that, I mean, able to meet a larger majority of people actually interested in wanting to do the work and interested in the things I am).
What are your thoughts?
