My parents desperately need their house cleared out and sterilized. It's always been a hoarding mess and they have blamed it on my brother, sister and I until now. This year the last of us had moved out and the house just became worst. They both hoard different things and my mom is known for buying the same thing twice and three times because she doesn't realize it's under a pile of junk somewhere. I have tried to help and both parents become defensive and change the topic. For every Christmas and birthday my mother has said she wants her house cleaned but when it comes time to get it done my father and her become paranoid and refuse to let me throw away anything. My father would go through the garbage after anything was thrown out and yell at me for tossing out perfectly good stuff. It's getting ridiculous and they don't see any issue and/or refuse to do anything about it. I don't want to embarrass them but I fear their safety and health living in this filth. Please help. I need to know how to clean out this mess without them stopping me.
