@TheInebriati there is one for children of hoarders but it's mainly a place to vent and fairly unsuitable for those interested in the actual disorder, and what could be done.
You will find quite a lot of people with hoarding disorder actually crossover with being the friends and families of other people with hoarding disorder. We are not as isolated 'other' as people want.
Some, including myself, will answer questions as best we can in order to try and help others gain a better understanding of a stupidly stigmatized condition. (though in my case later as I'm on lunch break)
I'm a 2nd generation hoarder who thought any genetic or learnt component had bypassed me, as my home bore NO resemblance to what I'd grown up in.
I actually have organized HD, (a poorly recognized HD presentation) and have long fought a tendency towards OTT cleaning, (OCD level) having initially grown up as literally one of the items in a classic extreme squalor hoard, without a bed, fed rotting food, and years of wearing the same two sets of threadbare tattered clothes, even to school.
My parent eventually was made to choose what to keep and what to let go.
They couldn't really. I didn't make the keep list. (did end up back there for a time)
My Dc's have been brought up so very differently and not around most of the stuff, or knowing what I really think, it's mainly not in the house and their lives.
It took a long time for me to realize the apple actually hadn't fallen far from the tree, I was just instinctively protecting my Dc's from a childhood similar to mine, and kidding myself.
Despite that protection one of them has shown hoarding tenancies from a very young age, (as did I with hindsight) the others haven't.
Those who think HD is all about meanness, selfishness or has to involve tottering piles, rotting newspapers, broken things, and animal feces, are wrong. Those things can also be present, some hoarders are also mean people, but many mean people aren't hoarders. Many with HD are generous by nature, it can actually be part of the problem.
Hoarding disorder is simply an insidious mental illness that sneaks up on people as a maladaptive behavior response to something else unaddressed going on, where the inability to discard slowly takes over an individuals life, until it forces spotlight attention onto the idea that something is going very wrong with them.
Many of us are very self aware and battling it. A dodgy industry and lots of misconceptions, and a desire to 'other' and hate, around makes it harder.
Chaotic hoarding and squalor hoarding are easy to recognize from the outside, because of how they present.
But HD can actually look ordered, clean, collected, curated, even spacious. It can also masquerade as nicely displayed collections.
It isn't what it looks like or where it's taking place (ie home, attic, garage, work, storage units, cloud, hardrive, Cd etc etc) the quality of the items, (or quality of info when digital hoarding has become a serious issue) or how it's kept.
There is only one test of 'is this hoarding?'
The depth of abnormal attachment for the keeper, the inability to discard and the extreme distress suffered when trying to, even when stability, family and survival itself is threatened. For some ending their lives becomes the only way out.
The 'stuff' is actually the symptom, not the disorder itself, which is why just clearing out the stuff without addressing the underlying disorder doesn't work, anymore than just force feeding an anorexic does.
I have helped several others sort out their homes, gain a better overview and have cleared two for others who had buried themselves including in a horrendous situation.
It's where I've got to as a work in progress with reasonable insight and overview and a hope of being able to cure myself, because it's become clear there is very little real help available.
