I think this song is about losing someone else. Like someone dying, when she says "you're so weak" or "if the one in the sky would take you I would cry" but she's telling this person sweet things, just to let him/her know how important was for her.
Maybe it could be the fear of losing someone who is loved and is completely fine but she's thinking the worst could happen.
It could be anything else, but that's what I think (:
