Must be the worst day of my life   Izza kizza   Girl      My first mistake was ltting you into my life (Yes it was)   My second mistake was allowing you into my bed (Laying in my bed)   My third mistake was loving you more than I should   Oh, I really should know better   My fourth mistake was sitting with you,   While you're telling me that you can't do this anymore      This must be the worst day of my life (x2)   And it's true 'cos all I wanna do is be by your side (My life)   This must be the worst day of my life (x2)   And it's true 'cos all I wanna do is be by your side (My life)      I'm walking home and listening to MP3s   Just how did I let you decide to destroy me?   I'm missing you, it crossed my mind that our heart will bleed   The love that I have left behind is gonna finish me   It's one of those days      This must be the worst day of my life (x2)   And it's true 'cos all I wanna do is be by your side (My life)   This must be the worst day of my life (x2)   And it's true 'cos all I wanna do is be by your side (My life)      See yesterday I called her back   The day before I called her flat   It ain't working, break my neck   Still it ain't cut me my cheque   A week ago I did my thang   Three o' clock, I missed my train   Tomorrow I thought we could chill   There won't be, yes, you won't, I will   The moral of the story like I told my cousin Corey   You see Cupid he will stab you in the back like Jason Voorhees   So he's got smoking cigarettes and got me drinkin' 40s   And the doctor said take two, and he said call me in the morning   It's the worst day      This must be the worst day of my life (x2)   And it's true 'cos all I wanna do is be by your side (My life)   This must be the worst day of my life (x2)   And it's true 'cos all I wanna do is be by your side (My life)      This must be the worst day of my life (x2)   My life
