Both of my boys have gone through periods like that while having a growth spurt. They would be very cranky and tired, and then suddenly, a week or two later I would realize they were 2 inches taller! Now I  know if my 8 year old DS ever takes a nap, he must be growing!

I bet if she takes a little down time, she will feel better, though maybe taller!

I hope she feels better soon! 

I'm glad to hear she is feeling better! It is so hard when kids are sick. 

If your DD exhibits those same bone tired symptoms and nausea and then complains of a sore throat...take her to the doctor to have her blood checked to rule out that she doesn't have mono. 

We had a bit of a scare today with DD.  She seems fine now.  Earlier today in PE, she fell off the bike she was riding.  She didn't remember everything that happened but she and the PE teacher said she didn't hit her head.  She seemed off during lunch, and at about 1:40 she vomited once.  I got her and took her to the doctor straight from there.  He checked her out and said a CT scan wouldn't be needed, that she wasn't displaying any other signs of concussion.  She was wearing a helmet, of course.  She's been resting at home and seems OK, aside from being shaken up by the whole thing.  No more vomiting and her energy seems better.  She complained about being bored at one point, which is always a good sign.  She had some Top Ramen and lemon lime soda for dinner.

She's had a tough couple of weeks and had to miss ballet again today, which bummed her out.

Poor thing.     Do they think she has a virus that's causing her not to feel well and vomit?

I think she's basically fine now, thankfully!
