My best friend (now dead) was like that. His apartment was filled to the ceiling with junk. There were rooms that were completely filled, I mean literally packed so full you could not even walk into them. Then there was so much junk in the hallways that the doors were blocked. There a was narrow little pathway up the stairs and a narrow little pathway from the bedroom through to the kitchen. The shower was so full of boxes it was unusable. There was barely enough room to get to the toilet and sink. I can't even begin to describe how disastrous it was. He was given notice on one place because of the fire hazard and still took 6 months to move it all to another place and did the same thing. Why they gave him that long I don't know. But yet "I might need it some day" or "Don't throw that away, it has memories". He was a good loyal friend but it was impossible to convince to do anything about the hoarding.
