I haven't felt good today

I haven't felt good today and it seems when I feel the worse, the kids act like the most terrible little brats EVER. I totally lost my cool with Sam tonight and now I feel like crap about it. It doesn't take much since my stress level is already so highly elevated with him. He just keeps pushing it and pushing it. Hannah was no help either. She just gets him all wound up and then when I get upset she's able to settle down while he's not. Everyone is tucked in their beds now and I'm not far behind!
