3) It’s all about a human connection.
The very first thing that’s done to help a hoarder on both shows is to get his friends and family involved. Not only does revealing how bad things have gotten help the hoarder realize how far off the rails he’s gone, rebuilding a connection with people who care about him provides an alternative to his hoard. Instead of trying and failing to fill their empty lives with things, hoarders get what they’re really looking for: love, friendship, and a human connection.
C.S. Lewis is one of the most quotable human beings ever to walk the earth and perhaps the wisest thing he ever said was, “Affection is responsible for nine-tenths of whatever solid and durable happiness there is in our lives.” You may not start a garbage pile in your living room or let 50 cats have the run of your house because you don’t have anyone in your life, but one way or the other, not being able to bathe in the milk of human kindness will leave a mark on you. Whatever else you do in life, don’t give up on reaching out to other people and trying to make connections. Your life may not literally depend on it, but the quality of your life certainly does.
