I don't wanna....

My house is disgusting. It is filthy and my animals make it stink. I need to clean it and I have a mountain of dirty clothes. My mother in law is coming to stay for a weeks with us on December 19th and I don't want it to be messy when she comes. I just have 0 motivation to clean it and do things. I work most of the time and when I come home I just don't want to do anything and my husband is the same way. :/
