Please don't let your fears and imagination get ahead of you. A diagnosis of Lupus (or other auto-immune disease) does not mean you WILL get organ damage, it simply means you MIGHT get organ damage. And you might get organ damage from many other illnesses as well.
See a rheumy, let them do their magic. With prompt treatment and reasonable ways of living you will get thru this, no matter how quiet or how active your disease might become.
Hang in there!
