Sometimes lyrics say it better than we can....

You've got a hold of me
Don't even know your power
I stand a hundred feet
But I fall when I'm around you

Show me an open door
Then you go and slam it on me
I can't take anymore
I'm saying baby

Please have mercy on me
Take it easy on my heart
Even though you don't mean to hurt me
You keep tearing me apart
Would you please have mercy, mercy on my heart
Would you please have mercy, mercy on my heart
