As the mother of a cfs sufferer of 16 who has had this condition for 2 years, I find it difficult to differentiate between "normal" adolescence behaviour in my daughter and cfs symptoms. Basically, my daughter gets EXTREMELY irritable and angry with everybody several days per week. We all have to "tread on eggshells while we're around her". On the other days she's just fine and a pleasure to be around. I was wondering if anyone out there has lived through the stormy adolescence years while suffering cfs, and did you find things improved - at least psychologically - as you left the teenage years? I also wonder if my daughter might just be suffering from reactive hypoglycemia. I can't get any doctor to test her for this here (in Ireland) as they all say "this test wouldn't be suitable". Basically, they haven't a clue about cfs (or M.E.) as it's known by here. I just feel like I'm up against a brick wall!
