Pepe,
I'm so sorry to hear that you will have to deal with Lupus too on top of your MG. Try to keep your spirits up even though it is sooo hard at times. My cousins wife has Lupus, she was diagnosed at 18 when she was pregnant with their daughter. She has had alot of ups and downs over the years but is still is a tough one. She is now 44 years old! I always tell her she is a TRUE fighter. Know that you are in my thoughts and prayers.
