I feel that there is a very good chance that this could be Lupus. The ANA that you had done is indicitive of several auto-immune diseases, however it is usually Lupus (in my experience) that will give someone a very high ANA. Along with that you also have many of the symptoms. The rash your getting sounds like the rash seen in Lupus. They call it a butter-fly rash because of the pattern it forms on the face. What is the titer of your ANA (how high)? I would suggest if your not seeing a Rheumatologist that you find one ASAP.
In regards to the thyroid, your TSH is very high and I hope your physician has started treatment. I have learned that thyroid problems can give you many of the symptoms of Lupus. However, the high ANA would suggest something like Lupus.
I hope that you feel better very soon and that I have been of some help!
