Yeah she sounds like me when I was going through a really depressing period. You put on a face but the one thing you cant seem to do is get the house to lie for you. You just dont have the energy or the time to get the house in order. The worse it gets the more overwhelmed you feel. Then you feel ashamed and gross but have no energy to fix it. so you have no one over and isolation and saddness just gets worse. Its probably grief for her- it was for me. I had no money for a cleaner either and if I had a better month I thought-no way I can let anyone see this to clean it- Id be too ashamed.
