It's very nearly a sonnet - the rhyme scheme is correct, but the scansion is a little off...

Failure
30 January 2005


fill the cracks in the face with my fingers
to overflowing, my last ascent belayed

flows because it must, blood lingers
in me, its stilling delayed

cling to the rock by gravity, not embrace;
thin air and clouds to touch, my wish befell

recoil a tube from my mouth, my last grace
spoke. Spiking fever or spiked vein fogs all else

check the rope unfrayed, picks and pitons intact
short, my legs shrink from the desert floor

swipe something essential; extract,
swab, suture my intent ignore

flightless, moorless, baseless, dropped
inoperable, insufferable; stopping stopped
