I don't want to go to school.
Why do you not want to go to school?
I have to endure being called names by those mean kids. There's also an exam next week and I'm afraid of failing as usual
School can be a tough time for some people. However, it is important that you go, because everyone does things they do not want to do, but have to do.
I don't want to do anything. I'm staying home.
That's a bad attitude to have because eventually you will be forced to do something or you'll end up like a bum.
