I am so sorry you are suffering this sleep disturbance. Sleep is so important to our health and anything that messes it up can be demoralizing.

Have you discussed your situation with a licensed physician? Sometimes there can be organic causes or factors involved in sleep problems and sometimes there are medical treatments that can lead to good outcomes. I have suffered many kinds of sleep problems over the years and physicians have helped me enormously. Of course, I am not in your shoes and cannot know what will or will not help you in your unique situation. Wish I knew how help. It can be really heartbreaking to have sleep problems!
