I think Joe Mattress has the most accurate interpretation. The song is wanting to go back to a happy place in your life, before all the change. "I've got nothing where I've been", "will you bring me THERE again." he wants to go back to the place he was before. "built a picture yesterday", "built a picture of a moment, my love". Remembering old times when things were better, now he doesn't know if he will "crumble or fly" and it scares him to the point of desperation to return to "where he's been".
