Hate school so much!?

I've just started year 10 (probably a different country to you so yes I just started). It's so hard. The maths, the english, science and chinese and japanese and the others. I'm really struggling and I feel like crying because I'm scared I'll have to repeat the year next year. I'm home schooled and I'm scared to even talk to the teachers on the phone because i get anxiety. My parents are scary when it comes to report cards, if I don't get A's or B's they yell at me for weeks and they are the scariest people on earth. What do I do? I suck at school so much but I want to get a good job when I grow up. I'm scared of the teachers and parents and have no friends. Should I just die? I mean my parents are going to kill me anyway, so I mays well just get it over with... Please help, nice answers, I know I'm and idiot but whatever. I wish I didn't suck at school, it's hard.
