I think I'm becoming distant from my friends?

You cant and you wont. There is nothing wrong with you.You cant force yourself to be in a group if you dont feel comfortable with. They are just different breed. They rely on each other and trust each other ... to a degree. Instead of getting involved into mindless stupidity, read more about the philosophy of forming social groups. You will discover the magic behind it and find out whether it is really worth it to be part of it or an outsider that controls it. The world is a lot more different outside of school and if you work on those skills, your survival and power will be limitless. Mark my words, your realization shows that you are maturing faster than the rest. Dont suppress it, feed it.
