Dear Ozziebear~
I can understand what you are saying and may be have an experience that might help. When I first was hospitalized my concentration was shot and a lifetime of reading stopped. Actually it had been stopped for a while. Up until then I read a lot, all sorts of things, and now I do again.
The problem was I'd scan a page, it would not sink in , so I'd read it again, and got nowhere. Maybe a bit like you trying to read a chapter and it not sinking in. My solution, well it was more luck than anything else, was to change to a different sort of book.
Instead of fiction suitable for adults I got a book of young adults' fantasy, and perhaps more importantly the pages were laced with puns and plays on words, so each few lines had its own appeal, quite apart from the plot. I've always liked puns and so on and my interest and ability to concentrate grew. Eventually I moved up to adolescents fantasy than later adult books.
So I'm afraid I've not answered your question about anxiety or OCD, but perhaps if you choose something you are closer to - or maybe even graphic novels - it might help. Later on you work up to other things.
