What to do in this situation with a school bus?

[JasonKeyes]

im really really worked up about this. So i was coming home from school today and i was going over this slope then down a hill and over the hill this school bus was coming up it from opposite direction, so i continued driving, then it turned on its lights and began to slow, but if i tried to stop i would be in the same spot the bus would be, so i just kept going. Then when i passed the bus he pointed at me angerly, but didn't open the stop arm till up the hill 10 more yards. SO i guess what im trying to say here is if i have broken any laws or if i should be worried?
