I think this song is a guy singing about a girl he's in love with who always thinks every time something goes wrong for her in her life, that it's the end of the world and she's so dramatic about it she thinks of just ending it all. He's saying, look just cause something doesn't go your way, that you shouldn't automatically throw in the towel and say its all over, he's saying he loves her and she needs to keep her head up cause he can't bare the thought of losing her.
