OK, a *very* slightly poetic translation here, but only a few things have
been changed. All in all, it's an accurate English version.

A Lament
O you who are dearest, you have flown.
Shut are all the doors and the windows
To my soul and inner mind.
But even if they are opened,
If the covers rise from the windows
And the gates flee from the doorways,
I will be afraid to open my eyes
And look at life without thee.
Tears now fall from those eyes;
Biting rain from a storm;
Blood from a fresh wound;
Icy water from a bitter spring;
A wild river down a steep waterfall.
I am enclosed;
High walls of grief,
High walls of pain.
Left in darkness
With swift fading memories of light.
Heavy is my heart
That falls into shadow.
A stone in deep water
Wherein fades light
And darkness rises,
Darkness rises
To meet me,
To catch me and hold me,
To flow through me and fill the vast hole
That was my heart.
A hole, a void, nothing,
And it is so heavy.
It is an overwhelming burden, this nothing.
O, why have you flown
When I do not have the wings to follow?
