Maybe you are trying to do too much and maybe you are undermedicated if your docs take the view that you are OK because the blood work suggests that. Most women take on far too much and have too high expectations of themselves. This notion of superwoman is promoted by the media. So is the notion of sick superwoman who overcomes all the odds. It has become almost socially uncceptable to be ill and not be able to function as "normal" almost a moral failing. It is very easy to be persuaded that we have to live up to completely unrealistic standards. It's hard to remember that energies fade even with a few years: the natural course of time and all sorts of life events take their toll.Although I dont understand why I am still so tired and ill when the disease is supposedly not active.
Perhaps too there is undiagnosed anemia or thyroid problems or some other condition causing fatigue.
