I wouldn't stress out about things. Feeling overwhelmed like nothing is done is completely normal. That feeling like you are cleaning and nothing is clean enough is called nesting. Many mothers do it before their little buddles of joy come. I am close to my due date as well and I know about the anxious nervous feeling that you are going through. Just remember when your baby comes he is going to depend on you so you need to pull it together a little and not mope around. Do what you can right now for him, because when he comes your time is going to be very full. I know that you may be experiencing a time right now where you feel helpless but rely on your family and friends to talk to, and you will overcome it. I am 7000 miles away from my mom and I call her everyday and it makes me feel so much better. Talk to your mom about what you are feeling, what you are afraid of and anything else that is on your mind. And remember they know what they are talking about because they have been there and raised a child.

FYI: statistically, first born babies are generally late - not early. Your mom's feelings have no bearing on when your baby will come. Relax.
