A kind of vent? (help me)

I've been super out of it lately and I'm starting to actuallly hate my friends. I don't even have a reason, they are completely fine and nice and supportave (kinda) but I'm beginning to full on hate them. I don't know why but I'm beginning to scare myself. It's gotten to the point where I'm putting them in Hunger Games simulators just so I can feel the pleasure of them dying. Apart from one, who I actually kind of like. But shes always hanging with the others in class.

What is wrong with me?

It's only the friends in my grade at my school too.

Well, the Hunger Games thing is weird, but I think you should at least talk to them more and try to figure out what you don't like about them.

They don't hang around me that much. They tend to stick amongst themselves and I have to be in the library most lunches.
