I have hit the wall. I am so tired and resting does not seem to be helping. Fro some reason, sleep has been eluding me lately. I have four more days to go (three classes of final exams to give and grade) and two dinners to attend. Then I will be done. I don't know if this is the MS or the low iron/B12 counts or a combination, but I have not been this fatigued since the first year when I was dx.
