The key word is I think, because I hear them talking about me behind my back, during class, for example just today it was the first day of school and these people that I don't even know was talking about me. Saying such things as, oh my god it's that Asian girl, I heard from my friend who was classmates with her that she has severe anxiety issues, and that she's a attention seeker.

....I don't even know them. I know that I should ignore them, I've gotten used to it thanks to this one incident where another guy in my high school math and chemistry class insulted me, and acted like I couldn't hear him, claiming that I am stupid and such because I thought it was another section of math instead of the higher section. Apparently to him, people can't make mistakes besides I thought it will be rude if I quit her class, so I stayed.

But really? It's happening again? I don't know if I should address them, ignore them or switch classes.

I would address a teacher or school counselor about this. I hope things get better for you

I agree Xiao, I'd tell somebody your trust. You do not need to go through this along.
