I used to be human

I used to have a heart that would beat for you
I use to have a breath that you casually take away
I used to have a skin that would tremble at your touch
I used to have a smile that you would make wider

Now I'm a robot

I don't have a heart to beat for me
I don't need oxygen for it was a waste for me
And I don't move my mouth anymore because every smile was betrayed.

I used to be human for you, but now I'm a machine because of you
