How do I change my life to be happy?

I'm sorry

but you seem like a perfectly rational person... I don't understand why these girls are excluding you..
One potential fix is to make friends with guys - it's a lot easier. I have a few female friends who were pretty much hated by the girls in my high school, and they compensated by making mostly guy friends, so maybe that'll help..

Things will get better when you go to college, you can start over..
Until then though, idk.. Maybe try to be more outgoing? Talk to some people you'd like to be friends with in class, etc.. maybe ask some of them to hang out sometime..

If they arent coming to you, go to them.
