I'm gonna take a shot I hope this helps,
Start with a image or feeling.
thats your chorus.
now right the verses using the same progression but strech the lyrics accros maybe two of the chords of the verse in the progressions.
now go back and color the important words in the verse with special chords.
But never speed up the tempo of the words greater than the tempo in the chorus
and let the highest note in the song occure in the chorus.
