Hm-m-m-m... well, Dancer29, you said your grades are fine. So you must be doing something right... maybe just doing a good job of picking out the right classmates to copy from? You also wrote that the teachers like you. So there again, it sounds as though you're doing something right. Of course it would be nice to have friends. But it's not mandatory & you didn't say anything about this being of great concern to you. Perhaps the stuff you're being taught is just not anything you're interested in. In that case, maybe it's simply a matter of finding some extracurricular activities that are of interest & that challenge you mentally. This may not make your classes any more interesting. But at least you'd have something to feel excited about outside of class. Beyond that, I'd suggest talking about this with a school counselor, a trusted teacher, or other person in real life.
