Prayers???

Miss Em is sick...and I'm hoping that it's the flu. It's amazing where my mind goes sometimes...scary places that no mother should have to think about. It is "just" the flu, right? She was fine yesterday, she went to bed, she woke up at 2:00am throwing up with a 103 temp. She continued to throw up throughout the night...just small amounts each time. This morning when she threw up it was A LOT and it was brownish red....which led me to think of blood. I was ready to call 911 or jump in the car and drive like a bat out of he** to the hospital. My husband calmed me down. We have broken her temp...but she is very lethargic. She threw up again, a smaller amount this time, but still the odd color? ARRRGGHHH!! I hate this! I'm sure that it's nothing, but it freaks me out that it could be something.
