Hi, have you read anything yet about what's called "Caregiver syndrome"?
Immune system effects are common with that, including susceptibility to infections, especially viral - which in turn can account for your cell counts. Unfortunately it's a condition not yet known about well enough in the world.
Your hemoglobin is really low, that alone can give you pronounced fatigue.
Have you been tested for lupus
Yes I have lupus and fibromyalgia but my rheumatologist says its not the lupus causeing my problems
