I think the "shake your head it's empty" means how people will go along with what the crowd is doing without thinking, like how when they hear a cool song they'll dance and shake their heads to the music without thinking about the lyrics. When I first listened to this song, it always made me want to shake my head, the guitar and Emily's voice are just so perfect, but when she gets to that line, I wondered what she meant and it made me stop and think for a moment. The last verse also made me think of an eating disorder, but it could be a disorder on so many levels. When she mentions coughing her heart out and not missing it at all, it makes me think about how people will just give up their opinions, emotions, and what they stand for just to go with the flow. Then after this, the person has no regrets, which surprises them.
