Playing My Part

You use your words as weapons,
Cut me deeper than a knife.
Though my blood remains unspilt
Still I feel the cuts as life
Spills out from my veins. I built
Such castles of hope this time,
But I built them on the sand.
Your attack will undermine
Them. No hope that they can stand
Against onslaught of that kind.
I will nurse my bleeding heart,
Lick my wounds and try to find
The resolve to play my part
On the stage within your mind.
