Hi ... was dx in 2003
good advice i have found ...
sleep well
eat well
don't sweat it
keep a journal (write your symptoms and rate them 1-5)
keep your own medical file (ask for copies of test etc)
reading, research (Lupus book by Dr Daniel Wallace)
get a good doctor ... one you can talk to openly & explains things to you
learn to know yourself ... only you know what and how much you can do
remember it is normal to be scared
know that you are not going mad (symptoms can be frustrating at times)
ask for help when you need it
know that you are not alone
keep posting
a positive attitude goes a long way in dealing with what ever comes along
