Hang in there! Decide on one babystep to do this afternoon and go do it. Just one. Remember, you can do ANYTHING for 15 minutes!
Having said that, I left this morning without making the beds and without packing anyone their lunch. So I'm going to take my own advice when I get home. I haven't cleaned a bathroom all week either, so maybe that will be my 15 minute task for this evening -- cleaning the master bathroom. Now that I've written it down, maybe I'll actually do it!
