What Do I Write

I can't seem to think of a thing, not a single poem or verse, all I'm writing down are the thoughts in my head, as I try to decide what line is the best, what kind of poem to write, is it a rap or lyric, or alliteration or ABC verse? What am I going to do, I can't tell which way is which, in this writing, and I can't find the words, that rhyme with me, I can't think of this writing, to much and not enough in my head. I still don't know what to write, I'm confused in my head, and I can't seem to get it right, what do I write, when there's not a thought in my head, how can I write, when there's nothing to write about?
