Aw, if you're having trouble with friends, why not just introduce yourself to somebody? It's not like they can judge you for saying hello, and honestly they'd have nO heart if they were to ignore you. And of coarse you have a purpose here people just don't see it yet. Try to push yourself to making new friends.

Hey, it’s okay. I’m in the same grade as you and my school is shoving this career stuff down our throats too, so you’re not alone! <3

hi whoever this is, I've experienced the same things, I find it really hard to open up to people/make friends which made me very lonely the past few years of my life. I changed school 3 times now and I just started in a new school this year. I told myself that this year I wasn't going to do nothing about it so I started with easy things, like talking to a fellow pupil, after that I felt more relaxed and I started talking to more people and now I'm totally happy at school. just build up slowly and eventually you'll get there xx
