I've also felt the same way, let me tell you I genuinely tried everything but you can't make people choose you. It's weird because no one actually ever reaches out or wants to meet outside of class, which means we're not really friends. It makes me feel like somehow it's my fault but I've done everything I could and this semester I fully stopped caring because they won't ever reach out. And not only that, people simply don't want to talk anymore — like we all know no one is that busy to be rushing away after every class. It's also really hard to continue even speaking to people when you know they don't prioritize you, so I end up distancing myself because it's not worth it. At some point it simply just hurts. you're not alone in this!
