AIBU to feel worried about my daughter's health? Does anyone have any experience of a young teen who goes though some weeks when they are utterly exhausted to the point of falling asleep on the school bus, in lessons and sleeping for easily 15+ hours a day at the weekend, and other weeks when the are completely fine and seem quite typical. My DD's mood and appetite is quite affected too. This has been the case for years but my dr has done blood tests and doesn't have any suggestions.
