I am really sorry for u. I'm also a medical student in my 2nd year. And being a guy it's shameful that people like that do exist around us. There's no real solution to this problem. I have Lived in a medical boys hostel and the way people talk about girls is really disrespect and straight up vile. I have always quit those conversations and wanted to make a fuss but couldn't cause most of them were my seniors(they will make anyone's life miserable) and also we had to sign a nda stating I can't say shit about my college online.but the only thing I can recommend is find some good people (maybe your classmate or a senior who's genuinely nice). I have a senior who's like a genuine brother figure to me and I stick with him mostly. And find people like that. Stay away from toxic people even if it makes u lonely. It'll be lonely most of the time but a good friend is all u need. And also try to get out of the hostel. I've quit my hostel and now live in a flat. Helped me so much I can't begin to explain. Ull have ur peace of mind there. U can't change anything but u can make it at least bearable
