writer's block

Have you ever had one of those times where you want so desperately to put your thoughts into words but every time you open your mouth the makings of your brain turn to putty and leak out your ears? Ok, so that was a bad visual but I'm kind of in that position right now. I've been playing with a melody/accompaniment that's been dancing around in my head for almost a year now. I wrote it sitting in the Eccles music building at Dixie in September of '07. It has extreme potential and it's one of the only melodies that I've written that I really truly like but I cannot think of any words. Every time I sit down to write words, my mind betrays me and I forget how to speak English. Now I know how a toddler feels.
