I've had trouble sleeping, too. Here are several things, and you can choose whatever sounds good to you.

1) the Law of Attraction = what you focus on expands.
If you focus on sleep anxiety, then sleep anxiety expands. If you focus on peaceful thoughts, then peaceful thoughts expand. This is a sneaky thing, though. You tried meditation to counter the sleep anxiety, right? I'm guessing that the purpose of the meditation was "sleep anxiety," therefore "sleep anxiety" expanded. The trick is to focus on a goal that is a positive, and it must be something _other_ than the absence of a negative.

2) I travel for work, and I slept better in hotel rooms than I did in my own bed. I associated my own bed with sleep anxiety. I had to change my habits to replace this association. Now I read something light/enjoyable/motivational in my bed before I sleep. I'm changing the association by repeated actions. I'm also changing the focus of my thoughts by concentrating on the book or magazine.

Best wishes!
