coughing up blood in the morning

[milo]

Seems there's little use to me
in writing too much on it.

Bleak extracts of morning
ushered out of smoky lungs.

Exeunt via lips,
descend no lower than the ground.

Small metallic streaks of red
among the normal junk.

Mortality in mucus,
washed away by tears of clouds.

regardless of what else is going on "exeunt" is the wrong word. 1. there is some disagreement with your verb which makes it second person direction, 2. while literally it means leave the stage, as direction, most notably, it means "leave our story" which it does not as the very next line picks it back up.
