I don't like music!!!

I don't like music, because I am not satisfied with the class. Dissatisfaction content is play the Trumpet. I play the Trumpet. Trumpet is very hard to play, because I have to blow lots of air. Sometimes, I have headache, so I want to take a break, but my music teacher does not give break time. That's why I have headache. Today I went to my form room in the 3rd period and took a rest. Maybe I take a rest in music class, then I'll get an F. Therefore, sometimes, I am very angry. I don't like music class, but I have to play the Trumpet, then I hear praise I am happy and like music. I want to change this rule. Specially, blow instrument. This is my proposal.(This paragraph is not criticism paragraph. Just a proposal paragraph. Don't misunderstanding please.)
