Might I make a few observations?
It seems to me that hoarders know that they are doing wrong. Why else would they think to make excuses?
I don't know where psychologists obtain their qualifications from but it seems to me that looking someone in the face and calling a spade a spade is, "off love.".
A dreadful harridan who only ever shouted at her three sons and husband whose spine was degenerating at a rate of knots was asked how much hoard was down to her replied that it could only be 30%.
Why, then, did not the, "experts" say that the sons could decide about what to do with 70% and she the rest?
Lastly, I see bad behavior being rewarded. It goes something like this...the hoarder is told that it's not his/her fault (diddums)...that the hoarder has done well to let things go...that the hoarder deserves the good outcome and is hugged and patted on the head.
Surely it's the put-upon who deserve the good outcome.
Looks to me that, "the bleeding obvious Sybil" is either edited out or is a monumental failure on the part of said, "experts".
Just saying.
don.
