My mom was/is a hoarder. She is still in denial about her illness and has a number of other psychiatric illnesses. When I was growing up, I would beg her to clean the house, it was so embarrassing, piles of papers, trash, all sorts of other crap and of yucky pests that flock to such a mess. She would always respond with if people were coming over, they shouldn't judge you for your house which I get the idea of but it was taken way too far. Her house was something out of the show "Hoarders", about 1/3 of the rooms in my mothers small house are completely closed off by crap and the rest have stacks of crap piled up, some parts of the house are just a little trail to get from one place to the next. On the few occasions I or someone in my family cleaned up some of the mess, it was swearing, yelling and abuse for days about how selfish we were.
My mother was reported to the county on at least one occasion, I was sure her house would be condemned because it was as bad or worse as some houses I saw on "hoarders". They weren't able to do anything except offer help (which she didn't take) because the county we live in has a very high bar for condemning a house, basically, there has to be an imminent fire hazard or structural hazard for them to take that step. I was really disappointed.
Littleflower - it is really frustrating dealing with a hoarder or those that enable them. The reality of the mess is obvious to everyone except them and they will do whatever it takes to maintain control of the crazy mess. I hope you find some comfort in knowing that you are not alone in this.
