You've got to think positive. It was my last year, and I kept thinking that in so many months I was getting out of this place, going to college, and I was likely never going to see any of the jerks from this town. Plus I plan on moving to England in a few years so that helps...
Just remember that it's your last year; this time next year you will (or should be, everyone starts/finishes school differently) be done with school, and all of those people you wanted to avoid will be gone. You won't ever have to see them every day again. And, if by some odd twist of fate you do actually see one of them again, just hold your head up high and ignore them. They'll be nothing to you once you get out of school, and they will never bother you again. :3
That's what helped me, so I hope that it'll at least help you too. <3
What annoys me?
That this person hasn't finished their roleplay yet. D:
They have a really good idea, and I really want to join, but posting isn't allowed and I feel like if I go to bed I'll forget all about it in the morning. D:
