You're in a hurry so this will be quick. Grab any old piece of paper and quickly outline what you think you need to say. Go really fast so that voice in your head that's telling you to panic has to shut up. Ignore everything in your world except the points you want to make. Do this with a pen or pencil and don't be neat. (But do be legible.)
You're trying to work while avoiding panic. You'll be easier on yourself if you follow a sloppy outline than one that looks like your sixth-grade teacher did it. Plus, you didn't put much thought into this outline, did you? So you want to feel free to take a detour or choose another route if the words start coming easily.
Now put this raggedy outline in front of you and start writing. If you stall, the outline will keep you moving forward. If there are important points you need to make, the outline will remind you of them.
The outline is there to help you, not limit you. If something better comes to you while you're working, follow your instincts. Just keep writing until you are finished.
