Help me translate this:

Hi!

there is a lyric:

"Cold was my soul
Untold was the pain
I faced, when you left me
A rose in the rain
So I swore to the razor
That never, enchained
Would your dark nails of faith
Be pushed through my veins again"

What does it mean?

untold was the pain and I faced with it

and when you left me I was like a rose in the rain

OR

I faced a rose in the rain, when you left me

Next:

So I swore to the razor
That you will never enchain me again

Will you your dark nails of faith
Push through my veins again ?

OR

You may enchain me, but I swear you won't push your dark nails through my veins?

Thank you!
