Im still watching it, but its great. I have exactly the same issue, its strange being so bad with ME and having so many not believing. When I do get a good doctors report which expresses things well that just gets ignored by others too.
Just to get my wheelchair, I needed THREE doctors backing this and their letters before it was believed I needed one (even thou I kept on collapsing on the floor of the supermarket when I got taken out with a support worker).
