I hope you are able to find some ideas to help you! 
I focus on sound, because sound helps me. If I'm trying to sleep, I focus on a repetitive sound that is not language, and practicing slow deep breathing. Sounds like crickets or white noise, or the window unit air conditioner. I empty my thoughts by focusing all my attention on that sound. I analyze the different parts of it, and try to find the point where the sound starts repeating. I focus on the rhythm and allow my breathing to become slow and deep, like during yoga.
