Is OTHER wrong in the post ? POST : So hey, first post ever. Neat. Also, long post incoming

Some context: I'm a high school senior (17F) and have been friends with a group of people since I was a sophomore. I kinda made the friend group and it expanded until junior year. I used to really really love and appreciate all of these people (I still do mostly) but after I went to a program over the summer and made amazing friends there, I realized that my friend group at home aren't the nicest. Another thing was that someone in my friend group also applied to this program in another subject but didn't get in.

My birthday was a few days after I came back from the program, so I invited both my friend group from the program and my one at home. I thought since everyone had similar interests, they would all get along. No. That did not happen. Everyone left and I got blasted on our group chat for bringing these 'outsiders' into a party that was just supposed to be a hangout with the close friend group. Alright. I'm kind of a coward (you'll see later) so I just shrugged it off and didn't mention it to them again. When the school year starts again, if I even mention the program, most of them (5/6 of them) get angry about it. Also, they always kind of make jokes about how everyone but me in that group is pretty (I'm not saying that I'm necessarily a person who tries to look good, but I wanna be pretty too lmao) and kind of assume that I can be the butt of jokes. Alright. They also all like to act as if one girl in the group talking to guys is a big thing since they all end up liking her (another thing is that they also blast me for being able to talk to everyone but never actually want my help in meeting new people). I'm the most outgoing, so I really try helping them talk to people like teachers and even other students. Great. I'll admit that some of them are really smart and have way better grades than me, but I really don't care because it's second semester and I'm graduating. What really upsets me is how they never acknowledge anything I do and always brush me off. 

The thing that made me want to write this was something that happened a week or two ago. There was a show at school that's the highlight of this semester so we all wanted to go. My childhood friend who goes to another school wanted to come so I was like "sure". Usually there's a huge line to go in but there's also food so we stop to get it then go to meet up with the friend group. I walk over to where they're standing in line to say hi and cut in (as we usually allow each other to do). In this first instance, all they do is turn the other way and ignore me. I'm like "aight" and go stand further back with other people. Then, I'm waiting by the bathroom when they brush past me without any notice. I usually would be fine if they hadn't seen me but we made eye contact. 

My other friends tell me to ditch them, but if I do, I'll be alone and I'm really not in the mood (yeet, ya girl's a coward), although I'm going to go to college and not talk to any of them. Am I the asshole for not wanting to be nicer to them (I've kind of been distancing myself) and/or not telling them how I feel about what they're doing?
