lupus, leukemia questions-white blood cell count, please help?

I'm seriously concerned with my niece. She put this on her facebook page. Now, the white blood count has been an issue for a few years with her, but no one that I was aware of (including the military doctors) have been able to tell why it is this way with her.

Is she really sick or just wanting attention? She has always wanted that extra attention growing up (crying wolf) so no one is believing this one either. Can it be true? Please enlighten her worried aunt!

She Writes

"My current condition, I've been told, could develop into either Lupus or Leukemia. Not sure which direction it will take, but I'm somewhat concerned about it. At 20k wbc in my cbc, I'm much closer to Lupus. Leukemia is at 50k wbc, while Lupus is at 35k. A normal person is between 8k-12k white blood cell count in their complete blood count [wbc/cbc] So mine's fairly elevated. It's been causing more and more helth problems as it progresses.

I'm getting used to the idea that I won't live as long as the rest of you, but I'm keeping it in check and checking on it as often as I can to make sure that it's not getting any worse. I want to be around with you guys for as long as I can be; after all, you're my family... Kinda stuck with me. =)"

Now, what is your opinion?
