I've got to ditto what Donna said... take your chorus you have written.. then make a story out of it, then reduce the story to versus...
sometimes, I start by just writing the words that seem relative, then create phrases or sentences, and expand until you are comfortable that you've created the story you want to tell that's relative to your chorus.. then make phrases of the important parts, getting rid of unnecessary words, and creating rhymes in a logical sequence that creates the beginning, the middle and the end.... good luck
