Loneliness, i guess

So lately I've been having drama with my friends. I'm a sophmore in high school and I've only had my two close friends this time which I've met in high school. But since last year they started pulling pranks on me, and I'm not the type of person to pull pranks. I just don't like pulling them on people. So we've been having "prank wars" and they have been wanting me to get them back, but when i did and told them it was a prank they both started ignoring me. I came to school on monday and they acted as if I don't exist. And I didn't have any classes with them that day so they just completly ignored me. But when i did have classes with them and one of them sat next to me, they moved a chair away and next to my other friend. 

And I was so confused, and all i was being was nice to them. I didn't say mean things to them, or yell at them for ignoring me, I just waited.

I waited for them to talk to me and then when i would ask them a question they would only give one worded answers. Then on the day before our spring break i told them both im sorry for the prank, and sorry for being nice because apparently i shouldn't have been nice, and I wished them a nice spring break and tried to give them cookies. But then they said that they weren't good friends to me and feel like shit around me. And I'm just so confused.

And its the middle of my break and they still haven't texted me and they keep posting things like "missing my bff" talking about my other friend not me. Now I'm worried that when i come back from break it's going to be the same. Them just ignoring me. 

And i know what you're saying, "Why can't you just make new friends?" well trust me i would, but it's too late into the school year for that and everyone already has their friend groups, and i doubt that a transfer student will come to my school in the middle of the year. Besides my school is tiny like 500 people. 

I just don't want to be all alone for the rest of the year. Because I always feel alone, and don't want to feel that at school too.

I hope your school year is going good, if you're in school right now that is.
