I hate my mom

I hate Spanish class and I wanted to take Latin but my mom just said take both so I did. My scheduale is all academic and I'm just so sick of it!  I want to Switch to a study hall for the first semester and then piano for the second semester. I want to SO bad but my mom just won't agree. My best friend happens to be in that study hall and she thinks I'm just doing it to be with her. She thinks I don't care about my grades but I was an honors student all last year. We just got in a huge fight and I'm just so mad and I don't know what to do! Please give some advice!
