Do you hit months or weeks that you just feel like you can't do it anymore?

I know we've had a lot on our plates, we've had heaps happen over the last 6 weeks or so. But today, not just today if I'm being totally honest, I'm over life. I can't cope with a 2.5 yr old whinging in my ear all day. Matilda needs some OT stuff done today, she's absolutely frantic, but I can't do it. I did my back in this week and it just decided today that was it... I can't even do up her seatbelt in the car at the moment.

I'm watching her cascade down today, and there is nothing IC an do about it, but get extremely angry and annoying with every little thing.... ARRRGGGHHHH
