Sudden stop (out of tears to shed)

It's not easy to witness
Someone's heart rate drop
Of course its even harder
When you heart comes to a sudden stop

Because you can't live without them
You made an unspoken deal
A silent promise to ensure
That your love for her is real

When you have their blood on your hands
As they whisper in your ear
"I love you always"
Things have never been so unclear

What am I supposed to do
My world is stationary, my love is dead
Everything has come to a sudden stop
I've run out of tears to shed
