Skysue, can you not do your shopping online? It would save you at least 2 hours.

Spixie33, can you clean on the way? I'm sure you have already thought of this maybe already doing but can you clean the dishes while the kids are having quite time or when they are sleeping? Althought, this doesn't mean you will be less tired.

And also If the kids are older you could ask them to tidy up too. Every little helps!

As some of us already had said your house doesn't have to be sparling and it won't hurt anyone if you don't do activities everyday.

Hope you will feel better soon.
