How to cheer up on the last day of school?

Today was the last day of school (8th grade) and my friends and I have been crying our eyes out! Half of my friends that I've known since kindergarten are going to different highschools. My best friend/boy friend that I've known since 3rd grade is moving to a different state, and we know the long distant relationship just won't work out... So here I am, sad and depressed and all I want to know is how to lighten up the mood and see things more positively. Any suggestions?
