What do 당신 do when 당신 can't pay attention in class?

I always start 백일몽 during class and I get yelled at for tapping my fingers 또는 doodling. Either 의해 my teachers 또는 classmates. I go to a catholic (I'm not catholic) private school and try everything, like playing with a pencil, doodling, tapping my fingers, and particpating during class. I keep 백일몽 and I can't help it. I also have tried taking notes but it's usually a class where 당신 don't have to.
Is there anything else I can do? I can't sit still...
