Shame on me, a fool for you

You took my heart from me
When you walked out of my life
Now I'm wasting away
I can't sleep through the night
Oh, you sucked the joy out of me
When you said goodbye

You told me you loved me
Then baby, you did me wrong
First you say it's meant to be
Then you start singing a different song
Now, you have me wrapped up in agony
But you're already gone

Why must you hurt me?
Oh and toy with my mind?
What do you gain from my misery?
Is this all part of your design?
Come now boy, tell me your story
You've wasted enough of my time
