why is this thing even part of my grade

I am so bitter that if a lemon licked me it would shrivel up and die. Every time I start feeling good about myself again someone is right there to remind me that I don't deserve to. God I hate people. Is it too much to ask that we all just be nice to each other? Or stop, even for a second, to actually consider that an opposing opinion might be valid? Honestly I feel some days like if I said the sky was blue, everyone would be lined up to tell me how stupid I am for thinking that. No matter how much evidence or facts I find to support my claim I'm just stupid and gullible and how *dare* I open my silly little mouth and contradict someone. 

If people are going to hate me no matter what I do, I might as well be an honest person. At least then I can tell myself they have a reason.
