It’s a terrible feeling because you know you hate school, but you are used to seeing the same people everyday, every class has a different personality and you feel like you will miss that class because you may not have anyone in it next year. It’s worse if you have a crush. You don’t know if you have any classes with them and it sucks. But, the good news is, it goes away really fast.
