If you are able to try and make custom pins to put on your backpack! There’s simple ones you can make with hot glue and tape and just make your interests on pins so other people can see!

OMG your art style is so adorabke! Everything is so matchy and cute! ✨

Start just looking around, and try to say hi to a person. If they give u THAT look, just go away as fast as u can. That's not the kind of friend ur searching. So, what I mean, just try to talk to the person u think is cool and chill about you, or talk to the person next to you. I know it's not easy. It took a while for me too to make new friends.
And YEAH it's scary to talk to new people, but just try. It's the only way.
Good luck!!

start by either talking to the closet person to your seat cuz you're gonna get to know at least them eventually I think
Or the person fartrst away so you don't interact as often bc ppl are scary...I think
That's what I can think of off the top of my head
