Hi Sue and Welcome!!!
My daughter has discoid lupus, but she's having the same issues. I think she may have SLE too. But she does have other health problems that also cause fatigue (Addison's disease).
You should ask your doctor to run some tests to see if anything else is going on (ie, other autoimmune diseases, fibromyalgia, etc) because people with one AI disease have a higher probability of developing others as time goes on.
I hope this is NOT the case for you! Good luck!
