Just leave then

Since the october break, there has not been a single week where I have attended all classes.
My motivation is failing, and I guess it just sort of dawned on me that no one likes me in my class. I thought I had friends but they tend to walk off without me a lot. Like, one person in "our" group of four says good bye to the other two before leaving but doesn't even look at me. Or today, after spanish, we were writing a test, and one of my "friends" finished early and patted the other on the shoulder and said where she'd be waiting for her. It's like, uhm okay, cool that you don't want to hang out with me.
Maybe it's because I don't care to take part in all the silly female rituals, like waiting for each other in the bathroom. It could have something to do with me just being indifferent towards them, I don't get super excited about things they squeal about and I don't consider seeing a cute boy around sometimes without ever talking to him intriguing. I guess, the less I bother to participate in these things the more they think that I don't want to hang around with them. I don't really know if I do, actually. It's just nice to be appreciated.
I catch myself thinking that maybe I can stand around with some people if I don't say anything so I don't bother them, because then they won't like me. At the same time I feel ridiculous trying to fit in with kids, and then I feel bad for looking down on them.
I wonder what it'd be like to not feel out of place for once. To actually be around people who are like me. If there even are such people.
