Who am i

I look in the mirror Someone took all the innocence in his eyes Say your goodbyes cause the me you knew is gone I'm not so fond of this guy I'm looking at I just want to take a bat to this illusion You call my name and I turn ghost Burn away the mask what's left there has been a theft all my feeling gone Numb is what I am I want to claw out those empty eyes My heart will never thaw I look in the mirror You said this isn't you then who is it
