Haik'd-up Villanelle

Don't ask.

Suggested by a poem by wyzguy over at AW.

A marriage of Haiku and villanelle.

why then, must I write
dredging up, disgorging pain
through the lonely night

when the muse takes flight
and the search for words is vain
why then, must I write

If the muse I fight
and the writing naught but pain
through the lonely night

when the muse gives light
and the words descend like rain
why then, must I write

If the muse grants sight
then not writing would be pain
through the lonely night

whether words descend like rain
or writing be fraught with pain
why then, must I write
through the lonely night
