I don't have a normal family and had evil people as my dub "friends" (in general), so maybe my opinion is out of whack.
Having said that...I often wonder if some of the trepidation about losing relationships is the result of brainwashing. After all, relationships with the dubs are disposable to a certain degree. Obviously painful, and a normal person would go through a serious grieving process, but it's not something you "can't take". Can't imagine maybe, but not "can't cope with".
The sun will rise tomorrow and there are billions of others on the planet with whom one can be close. Dubbery insists there are no friends like 'thee Friends', only walking dead prostitutes/rapists/Devil worshippers/etc. That is patently false, though it seems to be the basis for all the worry about getting dfd.
I'm guessing the bonds between a normal parent and a minor child would be one exception, though again, I have no personal experience with that so I don't know.
It's pretty typical of us humans to strive for all the benefits of a choice and none of the consequences. With this fading business, it seems to rise to malignant levels for some reason.
