I wonder why

I'm sick..I know I'm sick..I know to limit my contact with other ppl because  of being sick..being told three days in a row to not be around Sarah has me feeling paranoid and out of sorts..I have to work yes..but anything beyond that is just making me nervous...And talking to mommy keeps me on edge...And it just feels like I'm always stuck defending myself..over stupid things..am I really that stupid? I just feel like I nee  to be quiet and not do anything at all since I,can't even manage to be sock correctly.
