im in boarding school (ib) and my roommates suck ass

ok so i am retaking my ib exams and i am here at an ib boarding school because my parents thought i wouldnt study if i were at home. in a span of two months of being in boarding i have changed my room once, the reason being because my roommate would talk to everyone but me and in the room she would ignore my entire existence. so i changed my room to an ac room, and now my roommates are two girls. one is thai and and is indian, both of them are my classmates and both of them dont talk to me either, maybe occasionally. there are two more people, who are dudes. so at the breakfast table these 5 of them talk while they treat me like i dont exist. AND there this one girl pisses me off ( my ex roommate) cuz she pulls out the chair for this tall ass dude ( the only decent dude in school and is also in the same grade as me ). and i happen to fancy him a little bit so it PISSES ME TF OFF when she gets touchy with him. thats besides the point, the point here is my roommates as well as the other people in boarding who are in my grade ignore my existence and treat me like i dont exist. i feel like if this keeps happening i again wont be able to get the diploma

all this happening while i stay away from home, without my parents support is getting hard and suffocating.

advice needed ty :)
