Sending ya a big virtual hug!! Sounds like a lot is on your plate right now so do what you need to survive! If that means take out, paper plates, loads of free play, just doing the basic cleaning than so be it! This is just a temporary moment in your whole life but your whole life won't crumble if you slack for a few months. Don't feel guilty about it either...your making a baby so what better excuse is that!Tell your husband your feelings and ask if he can miss a few "man dates" and help out at the house and give you some time to yourself. Maybe switch every other weekend so you both get a break?
The other ladies have given great advice! Good luck and remember, this will pass and you will look back at it and know that you made it!
