I struggled with this too at the start, and still have to an extent. But now I like to think of myself as just more of a grown up than the girl that cries out for her ex boyfriend via a drunk facebook status update at 2am. Or the guy that posts about how he was up wondering if burger kind is open at 4 am.
You really just have to put yourself above that, and look down on it. That's what I've done, and like I said I'm for the most part over it.
