What else can I do to get you back?

I feel like you're slipping away from me. We've know each other for almost 10 years now, and we've never been this far away. We may be close, you know, same school, we see each other everyday, but it's not like it used to be, and I'm scared. I'm scared of losing our jokes. I'm scared of losing our connection. I'm scared of losing you. You're the only one that really understands me. You're the only one that knows how stupid I really am. You're the only one that knows how madly in love I am with Matthew Perry. You're the only one that understands my jokes. And I understand yours. 
I always thought that nothing could ever separate us. That we were bestfriends and that's how it was going to be, forever. Now, I'm not so sure. We're drifting apart, and I feel like there's nothing I can do to stop it. I feel like we're in separate trains going two separate ways, and the longer the trail is, the bigger the space between us is going to be. 
I've tried to be an intruse in your new group of friends. I've tried to push you away, so that it wouldn't hurt as much when we're actually away. I've tried everything I possibly can, and nothing seems to work. 
What else can I do to get you back? And yes, I am literally asking. 

What happened to us?!?
