You could be right. I really don't know. It shouldn't be that your CFS will want to cut off any treatment opportunities for you, but it doesn't surprise me that things like this can complicate medical relationships. Maybe your CFS doctor will be great, and really understanding? It's not worth worrying about the problems that could occur at some point in the future now though, and I agree with Calathea that it would be a good idea to take some time to relax and do something pleasurable. Sometimes these sorts of slip ups just happen, and have to be accepted as a part of life. I'm still hopeful that it won't lead to any real problems for you. Fingers-crossed it will all work out fine for you, and you'll be able to look back on this with a sense of relief.
