Nothing left

Take, take, take.
I gave you all of me, big mistake.
How could I have been so naïve,
naïve to see that you were using me.
Taking everything you took from me,
bleeding my heart dry, deserted.
sucking the life out of me, why did you?
Why didn't you just let me be,
let me go, so I could love who loved me,
but no, greedy beast wanted all of me
and the more I gave the more you took from me
till there was nothing left of me.
