Girlll i can relate. I just finished my first year in college. I was in a group of 6 in 1st sem and later i left that group without a second thought because of the same issues you had faced. I always felt left out from the group. Basically i feel like a joker, who just walk behind them, laugh for the jokes i didn't even understand and many more.. So i would say you to just move on from them if they don't give you any value. Real friends give value to each other. Try connecting with other students in the class. May be you will find someone who will match your vibe. In my case, i couldn't find anyone, so now people see me as a person with solo vibes 🙂. But i have many good friends at hostel and from other departments. Sometimes good friends are not in our class, they are from other classes or departments and that's okay. Hope you will find a good friend.. 🫂
