                     G (320003@1)       G+4
                 I have been out of my head
                          Gm7
                  Hanging on by athread (x02210@1)                        Gm7
                 To aworld (x02210@1)I'm missing

                      G (320003@1)         G+4
                  And I , fall asleep at the wheel
                             Gm7
                   Getting looks that could kill
                             Gm7
                  Because I'm not listening


                    G (320003@1)             G+4
                  There must be abetter (x02210@1)way
                     Gm7
                  There must be away (x02210@1)to change 
                    G (320003@1)            G+4
                  Both of us are scared to say
                    Gm7    
                  So this is all or nothing


                    G (320003@1)                           G+4
                  Never know what the future may bring
                    G+4                                   Gm7
                  Leave the past 'cause it don't mean athing (x02210@1)                    Gm7
                  So this is all or nothing.    ( rpt )
