Driving Nails

Folks,

I think we all know who the protangonist is that is speaking in the first person singular below. I was caught by the phrase, "Driving nails into my soul, angels from my door..."

Driving Nails
by Demon Hunter

[Verse 1:]
I was the light
I was the quiet heart
I was the place we used to dwell
And when the cold would tear your life apart,
I was the warmth that you had felt (What have I become?)

[Pre-Chorus]
What have I become?
Thoughts like shadows swelling through my mind
What have I become?
Something else inside...

[Chorus 1:]
It's driving nails into my soul
Angels from my door
Driving nails into my soul
Something inside...

[Verse 2:]
I was the blood inside your broken heart
I was the stone that you had held (What have I become?)

(Pre-Chorus)

[Chorus 2:]
It's driving nails into my soul
Angels from my door
Driving nails into my soul
Something else inside...

(Chorus 1)

[Bridge:]
I close my eyes
Search for you
Retracing every step

(Chorus 1)

Nails into my soul
Angels from my door
Driving nails into my soul
Something else inside...

(Chorus 2)
