Relax, Delissa. I've had the same experience. Sometimes I knew what I wanted to get rid of, sometimes not. So I let go of my thoughts, just let them drift, and told my other-than-conscious mind that I had faith in it and it would find what it needed. I keep my conscious mind on visualzing what would happen when I got what I wanted, or visualizing the field, or the view off the mountain, and just let my other-than-conscious mind have at it.
