i f hate my classmates

I'm so sick of my classmates. Like they all drink alkohol and somkes. It is so stupid to me.Cuz like why ruin your health at such young age? to be cool? pls begin cool is literally a relative concept. It is so sad that some people are doing that to impress someone. Probably most of them will forget about thoes people who they wonted impress. And most of my classmates are so rude for no reson. Like they be staring at me like I have killed their mom or sth. Like who hurt you bro? I can literally never talk to them and they still will do that shit. AND THERE IS ALSO THAT ONE GUY. I CANT STAND HIM. Like he is the worst person i had to ever deal with. HE IS misogynistic,sexist,says he belives in God when he does not obey the commandent of love and is very steroetipical Christian, he is homofobic, rasist and male manipulator. HOW CAN ONE PERSON KEEP SO MUCH HATRED IN THEMSELF? He says that this  is bc his girlfriend left him(lmafo I wonder why). HE WAKES UP AND ALWAYS CHOOSES VOILENCE.
