First thing I would address is her high RT3 and low T3. Mine was at 28.1 after a bout with flu/sinus infection due to low iron/ferritin. Maybe hers is low as well only blood testing can tell. Cytomel can fix her elevated RT3. Here are a couple of good links:

It was probably the worst I’ve felt since I had the flu many eons ago. Tired, cold, wanted to nap, mental fog, just to name a few. Good luck and keep us posted
