There's Nothing Now

There’s nothing now that I can do for you,

and how it hurts my heart that this is so.

My sky has darkened from its sunny blue

as I discern that yours is thick with snow.

I always held to what I knew was true –

only to wonder now if I did know.

We were each other’s shelters once; that’s gone.
Like swords: the cutting rain, the piercing sun.

A combined ottava rima / ghazal, for the Poetic Asides ottava rima challenge. (Or rather, a quasi-ghazal – since, among other things not present here, a ghazal should have at least five couplets ... whereas an ottava rima cannot have so many.)
