I am about to clear my late uncle's belongings and I am extremely overwhelmed. Started out collecting (books, manga, vinyl, laser discs, tapes, CDs, DVDs, Blu-Ray, comic books etc), and descended into hoarding eventually. Has storage units too. Place is filthy, got a week and a half to clear it all before I need to hand the keys back. People don't understand what hoarding is like.
