SO sick

I am so sick of what my parents said.They always say"You must do this ...Keep reading..."

Sometimes I want to play Ping-Pong,but they will say:"You can't do that!You must study hard!Do you homework!"That's disappointmented me.

I just wanna some time to relax.Why must I keep studing for such a long time?I try to talking with my parents,but they think the child must listen to the counsel of your elders.

I think child should have relax time,like a bird of freedom.

IF I MADE SOME MISTAKES ABOUT GRAMMAR OF CERTAINLY,PLEASE POINT OUT~(Thanks!)
