Missing yourself

There's a void chamber in your heart
It seems that's why you act this part
My strings will wear away before I can
Turn you into a song, and forget what we had
The cold where warmth should be in your bed
Reacts violently with your body against it
Sending shivers down your spine
My absence sends a sign that you're missing something
But you're missing the point
The one that you're missing now is only yourself
