Am I in the wrong for this?

I need some advice. Am I wrong for this one? So at the beginning of the year, I met these 2 girls and involved them in my friend group, which only had 3 people including me. (One being one of my friends since 2nd grade, and the other one being my twin sister.) My friend from 2nd grade, let's call her Sobbing. So this kinda all started when Sobbing went on a trip back to her home country for a month. These 2 new girls, Banana and Joy, suddenly got super close to Sobbing. At first, I didn't mind. But then we started getting into arguments. Our first one was because we left to go to the library, and they said they were coming but never came. Then after that, I had class with the 3 of them, and I had the WORST stomach ache, so I wasn't doing my best. The teacher called me out for it, so I told her I had food poisoning. When I went to work with them, I wasn't doing much because I felt like I wanted to vomit. They stopped talking to each other just to tell me to go home if I wasn't feeling well. As I left the room, I broke down in tears because a month ago they all would've dropped me off, and I felt like they only wanted me out. After that, for some reason, we started ignoring each other, which I didn't want, so obviously I was heartbroken. We had class together, and they completely ignored me. They finally talked to us when I asked them what the problem was and accidentally broke down in tears. I remember them telling me that they thought we wanted some space (we being me and my twin sister). While one of them comforted me, I glanced over and saw Sobbing not giving a care in the world. Things were casual for a while after that.
But recently, I walked away from them when they mentioned this TikTok. (It was the trend "These kids at my school. Awful. Have you seen The Outsiders? Call me Ponyboy.") I did this but with ORV and KDJ. So surprisingly, it landed on Joy's fyp, and they teased me for it. I got kinda pissed, so I walked away. (My bad lolol.) They then ignored me again. But then I decided to make up with them by writing a contract like Won Dae's so it'd lighten the mood. But when I got the contract back, they wrote that I had walked away from them 3 times mb homie and that we ignored them first. (We didn't. They sat next to us while we were playing Papa's Burgeria, and when we had to go to class, they just walked away together.) So on Wednesday, during the last lesson of the day, I tried to make up with them by apologising. But I guess God had different ideas that day because Sobbing and Banana asked if the teasing was the problem since I had walked away from them multiple times. So I made a joke trying to lighten the mood by saying, "Oh haha, sorry. That was the apex predator in me walking away from their prey." But they responded with, "That doesn't make any sense." I know damn well that if we weren't arguing, if it didn't make sense, they would've laughed at me because of how stupid it sounded. I got so pissed that I skipped class and did one of my revision maths papers instead. And now they completely ignore me. I'm really pissed because Sobbing over here isn't the best lad out there. She switches up on her day ones, as we can obviously see. Oh, now that I remember, I was asking them if they wanted to go to the mall. One of them said they didn't have money because they were saving up for a con. Totally cool. So I suggested Costco instead because they have really cheap meals there. (I was rejected.) So I even offered to go to the park together, but apparently enjoying nature is too boring now. Then Sobbing said she had no money, which was funny enough since her mum always gives her $50 when she goes out. (Sobbing is also on the greedy side. Once we all went to the library to "study" But there was a mall nearby that we wanted to go to. So my twin had spent her share on makeup, and I spent mine on the ORV novels 2 and 4 and Liptons.
Banana and Joy saw we had no money, so they offered to buy us a meal, which they did. :> So we felt bad and ordered ice cream for all of us except Banana since she's lactose intolerant. Funnily enough, Sobbing didn't pay for shit and just greedily tried to get the biggest serve while insisting she'd pay for the next meal.) P.S. Sobbing is racist! I remember going over to her house when she casually said a racist slur, and when I confronted her about it, she just said, "My house, my rules." Now I don't know what to do next. Can somebody please help?
