Wow - it sounds like you're overwhelmed. The best advice I can give you is to take one day at a time, it's the only way to get through it. Are your children old enough to help take some of the daily chores off your shoulders? They may resist, but if you can organize them into a team of helpers so that the whole family is involved it may help. And it will be very useful to them in the future to know how to do laundry, cook, clean, etc.
