I think this song is talking about many things and has different meanings. I think to some people it could be about mental health issues(Michael), and I think to some others it about it failed relationships, about leaving them and feeling like it's ok to hurt people. I think it's about feeling like a f**k up and a outcast. I think it's about fighting demons and feeling like nobody gets. I think it's about being suicidal and broken. It's about feeling torn and having mixed feelings. It's about feeling you hurt everything in your path. I feel like the boy are telling the fans that feel this way to move on and enjoy life:)
