From Impluse, by Ellen Hopkins.

The Thread

Wish
You could turn off
the questions, turn
off the voices,
turn off all sound.

Yearn
to close out
the ugliness, close
out the filthiness
close out all light.

Long
to cast away
yesterday, cast
away memory
cast away all jeopardy.

Pray
you could somehow stop
the uncertainty, somehow
stop the loathing,
somehow stop the pain.

There is another verse to this poem, but I find the first three to be more relevant.
