Rant

okay. So i officially am extremly annoyed with my friends. Where do i start?

So my friend, we'll call her Matilda, invited my other friend, we'll call Bethany, to go with her to the basketball game and then afterward go back to Matilda's house. bethany said she couldn't go because she was having a going away party for her aunt because she was moving to Arkansas. Matilda thouhgt that was fine until she got on facebook and on her news feed saw that bethany had gone over to a friends house that Matilda doesn't like. Then she got really mad at her for lying. But it was a party and bethany probably didn't say anything to matilda about it because

(1) she hates those people and doesn't like bethany hanging out with them and

(2) She felt bad Matilda wasn't invited.

So now my friend, we'll call Samantha, is siding with matilda and they just don't seem to see bethany's side. bethany is one of my really good friends so i told Matilda if it bothers her that much. But she won't confront her. So I got a little shitty with them and pretty much told them to grow some balls. That was at lunch. During there next class they talked about me and decided that i was extremly stressed out and that was why i was mad. but i wasn't mad i was just expressing my opinion but they just don't seem to get that so the next couple days i am sitting at a different lunch table. So...

(1) Am I being a complete girl about this?
(2) What do you suggest I do?
