A Murderer Inside lyrics

I am a murderer inside... Just have to wait My head rush has gone, Just have to wait To lay may pain outside. I'm a killer when I get all alone Would you forgive me ?... I am alive and I am cruel. I sometimes die when I strangle my all But nothing can get out of all my sides I'm a murderer inside. Please forgive me I want to hurt nobody Please forgive me The only one I kill... Is me.
