KC, have you had her evaluated? Or tried a diet intervention? Sounds like a dairy/soy/corn/gluten intolerence to me. Or food dye. Can make all the difference in the world. Trust me. Took myself off gluten, and I'm no longer a raving psycho bitch!
i think she's just trying to cram as much life into every moment as she can. our diets are pretty darned clean. we figured out the soy/food additive stuff a while back. it DID make a difference. she's just INCREDIBLY busy.
