Tomorrow I’m gonna have orienteering with my class. I can’t stop worrying about it. I almost throw up every time I think about it. I wanna get a good grade, I wanna impress my teacher. I don’t wanna get lost in the woods or go the wrong way. I don’t wanna disappoint anyone. And I don’t wanna have a panic attack and cry in front of the whole class and my teacher, which happened last time we did this. 

So please what should I do to calm down and make the best out of the situation? I can’t control my worrying, I’m not gonna be able to sleep. Please help me.
