Mad Cow??!!!

Mad Cow disease?? Really this is the only thing that can possibly describe this, and by this I mean Tessa. She has been on and off sick for a couple of months, and now she is just acting plain crazy. So here's what she did today. She dumped Gracie's whole chest of drawer of clothes out on the floor, not only out, but threw them across the entire room, not only that, she has thrown every shoe they have out of the shoe bucket, and took the pictures of their names off of the walls and took the glass out of the frames. This probably sounds like I wasn't watching them, but honestly all this took place in the span of me trying to fix supper, wash clothes, put up groceries etc..... I don't know what to do. Right now, my heart is racing and I feel like I'm about to lose my mind! Is this normal??? Do these describe Mad Cow disease, or mad child???!! Please let tomorrow be better...
