since then, people at my classroom that were on this thing been acting like they are trying to help me but i don't believe in any of them.

I used to be in that sort of toxic mode. but it wasn't toxic for others - only me. it seems like everyone's a fake, a liar. that's definitely anxiety acting up - i'm talking from experience. after quickly getting to know some people (getting to know them real good in a REALLY short amount of time, a lot of built up trust pretty much) (well, actually one person, just a girl) i realised that as unreal as it looks (you'd be thinking how can someone like them care for someone like you) others CAN actually care for you and want better for you. i know that it seems unreal and i've been there. honestly, i still am, to this day it's trust issues that are screwing shit up with people, yet i still manage to trust that person. try it, try to change.
