I can't sleep

I can't sleep because I have this stupid review tomorrow at school and I know it is going to end up being bad and it will just make me so mad...
It's already 3:06am so that means I have to get ready for school in a few hours but I just can't sleep and I am so tired.
It's the thought of what will happen or what I know will happen that is stopping me from sleeping and it is so annoying >.<
I can't wait to leave that school. Only like 7 weeks left but it seems 893573498573 million years away
