Tomorrow is another day! You might get a second wind and start cleaning. I find that iif I do just one thing like load the dishwasher- I go dish by dish and try not to look at the dirty dishes as a whole or I want to give up. After I do the dishes, I think "I'll just sweep the kitchen floor..." Then "I'll just mop the kitchen floor..." And before you know it the kitchen is clean. Then I put on music and do the livingroom, etc. I dont think of a whole job just one dish at a time.
