I'm so sorry that you are having trouble sleeping. Have you tried establishing a bedtime routine- doing the same thing in the same order every night before bed? Over time, your body and mind should associate this routine with going to sleep. The process can take several months to become effective. Not being able to sleep is really an awful thing.

The three things I do every single day when I get up are decide how to set the room for sleep that night. In other words, I make the bed, clean up the area to be ready for sleep before I leave the bedroom.

The second thing I do is make sure I drink and or eat enough liquid to keep my anxiety resting levels within normal range. Keeping track of your anxiety levels along with a menu and movement log will give you an idea of the patterns of thought.

The third thing I do is stand in front of the mirror and make nice with myself. I do this in the morning when I get up and in the night before I go to bed.

Hope this helps.

Two things that have helped me were hypnosis, (a little easier to let thoughts go), and a magnesium drink before bed. I buy mine in a natural foods market, but Amazon has them online. I use one without anything else except a mild lemon flavor. (Some have calcium and magnesium.) I give my kid some before bed because of difficulty settling down. It helps me tons. My anxious thoughts can keep me awake, too. Insomnia is a bane.
