One thing that has helped me, later on after I left school, everyone else is the same as you.
Think of the teacher, they are desperate for you to do well. Ask questions when you can, maybe by e-mail if you can't catch them face to face. They are happy to help, they want their students to thrive.
Same at work, almost everyone is keen for you to do well, they want to teach you and support you so you stay and make their own lives better at work with your support as you grow.
If somone freezes you out in the corridor, it's because they have something on their mind and did not even notice you.
Someone gives you a funny look, it is most likely they are thinking of somthing else and just happened to be looking your way.
Don't imagine that you are the center of the world. Thank god we are not; we just play at the edges!
Also no one can hear your thoughts, also thank god for that.
Be gentle with yourself. Everything takes time for everyone.
It takes time to figure out that balance of aloneness, getting space, yet not letting yourself get isolated and ensuring you have a few people you can share time with, it helps you feel real.
I'm still learning.
Breezy and Pleasant
