Sara Radle can t go on

I can't go on
You see, you're just no good for me
I've got a bone to pick with you
I can't go on
You see, you cause me such pain and misery
You've got me down
You've got me blue
I can do this no more
I give it all, and don't know what for
There's only so much I can do
Can't do this, it's a fact
You took my heart, now I want it back
My greatest fear has now come true
