I wish I could give you more comforting words; unfortunately I am unaware of any. I remember back when I was forced to go to school. I had very much the same situation you have. All alone, everybody only used me for their own benefits, and everybody else was always completely irate when I tried to explain my feelings. I finally managed to drop out of high school, and that was the worst option I could have ever made. I struggle daily now to find enough money to live on. Sure, I have my GED, and some might say it is just as good as a diploma, but my ventures so far in life have proven otherwise.
My best advice to you is to find somewhere else to go in your mind, like in Happy Gilmore. My personal one is to just daydream about a world full of anthros that got along with each other instead of fighting and being greedy, like humans. I don't know if this method would work for you or not, but if you haven't given it a shot, it may be worth a try?
