Freaking out

I went to the nurse practitioner today for a follow-up on some lab work I’ve had done over the last couple weeks- some blood tests and a 24 hour urine collection.  (Let me tell you about doing that- its no fun, you pee more frequently because you’re obsessing about collecting it. And also you have to refrigerate it.  Ewww.)
So my one blood test shows I am positive for an autoimmune disorder.  Possibly lupus.  She’s referring me to the endocrinologist.  I am pretty freaked out by the whole deal.  One of my aunts has lupus, so I know its totally something that can be lived with- she works full time as an LPN at a doctor’s office and keeps up a busy life.  But still. Me, have lupus?!  Totally scary. 
Send good vibes my way would you?
