i hate my life all because of school

i know most people will be judging me for this and accusing me of being dramatic, but i literally only have my school to blame for how my life is rn. i was always the cheeriest person in the friend group, the girl people thought was always happy, and ig that was true at the time. but i went into a certain ib jc this year and it feels like my life has gone from heaven to hell. no one around me is pleasant to be around and it really really sucks. im not even kidding when i say that my classmates (and schoolmates for that matter) are the most entitled, spoilt brats ive ever interacted with. i was working on a pair group coursework with this girl, lets call her R. she refused to do any work or schedule any online meetings with me, and when i told her id not give her credit for the work if she freeloaded, she told me 'im rich enough to make you stfu'. thats actually crazy coming from a student???? i obviously ended up having to do the work all on my own and guess what, the teacher didnt bat an eye during the presentation when she wasnt able to present the slides properly and gave her the same grade as me. did some research, turns out she has an uncle AND had a grandfather in the school's board, so the teachers dont dare to offend her whole family! another time when we were going out for class outing on a short day, everyone wanted to go to sentosa so we had to figure out how to get there first. before we met up, i sent a screenshot of the route by bus+mrt in the class chat, no one said anything but a few people reacted with the 😂 emoji. i was like ??? then i texted a smaller gc with like 5 ish girls from the class im closer to, asking why everyone was silent. they literally told me that public transport is for the poor and that its 'giving mid-tier jc energy to take mrt'. WTF??? i was so shocked i didnt know how to reply. obv someone ended up booking 3 7-seaters on grab for $45 each which i literally didnt want to but had no choice. the students here are actually INSANE, the secondhand embarrassment i get from my classmates and even my friends makes me not wanna go to school anymore. if i can i dont even want to put my ib diploma on my cv once i get into uni.
