Oh Nox you poor thing!
It sounds like the sleep deprivation may be taking its toll on you, I know I often feel the way you are when I've had a few particurally bad nights in a row, and especially when your DS is refusing to nap, I hate those days!! Is there someone who can help you out to get a little rest to make your head a bit clearer? Things always seems so bad when you're so tired!
Hugs to you babe!
