Why am I too tired to make an effort or do well in school?

I'm a freshman in high school and I absolutely hate it. I hate graphic organizers, I hate data tables, I hate charts, equations, homework, tests, exams, reviews, nitpicking teachers, other, intrusive students and "authority figures". History is really the only cl that captivates me but I really like medieval history. I don't really like any of that American History crap where we learn about World War II and then the next day why it sucks to be white because of something your great great great great great great great grandfather did. I usually get an A in history, but I get Ds and Cs in everything else. I even failed my math final. I'm heading to a private school next year as a sopre, but the only reason I got in is because my little brother got in too and they didn't want me to feel bad. I hate the teachers and their condescending attitude and the whole 'mentor' role really doesn't feel natural to me. I am always too tired or indifferent to do my work and I hate staring at a blank graphic organizer or something like that. My mom screams at me and calls me stupid, my dad doesn't care, my teachers are *****, but my friends say I'm smart because I have a large vocabulary or something like that. Sorry for this Hadrian's Wall of text but I'm really confused here. Does anybody else feel this way? Why is it so hard for me to just sit down and do something, or study, or whatever. I hate this. I'm always behind, and I always seem to be thinking about something else. Am I stupid or what? Please help me out. I really don't get it. Again sorry for the mive question but it's pretty specific and I'm thinking about getting therapy.
