Can I skip iv since I don't get along with any of my classmates and it just causes me lot of stress.

I'm in my last sem of engineering and i was in a big group in my first year which consisted of almost all girls of my class but i realized it was very toxic for me as i was treated like an extra and kept away from plans and I just felt excluded and all those backhanded remarks made me take my self respect back and stop hanging out with them and i quickly became one of th uncool girls of the class so i thought of hanging out with the other girls which were isolated but they thought hanging out with me would make them a loser ig and they were never sincere with me and would only come to me and talk to me when they felt alone. I do have friends in other classes due to hostel and clubs but in my class idk I just can't bring myself to talk to them anymore given how they treated me. The amount of times I've cried due to this in my second and third year has made me hate these ppl. Now we need to go for iv and I'm stressing about being lonely in a trip i have to pay so much for. Also iv(4 days) is just an excuse for a trip and the industrial visit would just be like 1 hour. Being excluded from everything during the iv is going to break my heart but I know it's gonna happen. Edit: the boys of my class are a big group and they just hangout with each other and they really respect the girls I'm not getting along with as they are really pretty but not on the inside. This really taught me how looks matter I'm not a ugly person but I'm not that beautiful either. I just want to know if it's allowed to skip iv?
