Help!

So me and my boyfriend of 2 years just broke up. It was mutual because he is 18 and I'm 15. And I would never wish for him to get into trouble over me. While it was mutual and we're still friends I am still upset as he is. What are some things to do to not cry and just not think of it as the worst thing possible? And there's still a chance that we'll still get back together in a few years because we're gonna be friends. I just want some things to do so I'm not bored and constantly thinking about it.
