My meaning of this song is that he's having a hard time in life and is just trying to get himself back on his feet wether it's a girl he's having a hard time about, or if it's family. Either or. For me when I hear this song it's family hard times. When he says "just keep me where the light is" I think he's refering to the brighter (happier) times in life. He just wants everything to be okay. .
But that's just what I think. .: S. Lol.
