That really doesn't give any of us much to go by if we're trying to help you... can you be more specific?? What I find that helps me when I'm suffering from some writers block is just to simply take a few days off of even trying to think up lyrics... and just work on playing guitar. I like to listen to a lot of lyrically heavy music too... this helps me get ideas about melodies and different phrases and ryhmings that are used. Som of my favorite stuff to listen to to get good acoustic songs (depending on my mood) are Jason Mraz, John Mayer, Staind, and Dave Matthews. But you might find that not to your taste... so whatever works for you.
