by this time of the year, I was asked to drop english ext 2 by my teacher precisely because i hadn't done anything constructive, useful or good, (eg bad poetry).
I wouldn't stress yet, save that for the week before when you are going crazy to perfect every letter and punctuation in your major work.
How i go through was working with a structure, a backbone for your suite or collection. hope this makes sense. like i wrote around 20 poems, and 9 of them were the different phases of the moon. so i started with these, and it got so much easier. maybe you could try this angle.
haha 666_blessings, procrastination IS a wonderful thing...
