I fear my school!!

I keep gettng tese nightmares about going back to school on the first day, and still having the teachers I had last year, and its the ones that I absolutely despise! And its just absolutely horrible, even if one of the teachers I'm talking about doesn't even teach the on-going grade I'm going into. I keep crashing out in my nightmares, and then killing myself in them. This has GYATT to stop.
