While searching for something else altogether online, I came across an official government guide for social workers dealing with hoarding. Was a bit confronting reading it, but it had some helpful take aways.
-Yes, my comment a few days ago about hoarding having a security aspect was correct.
-The practice of sending someone in to clear out all the junk is not officially recommended, because it causes too much emotional distress for the hoarder, and if they're accumulating for security, they will amass a new hoard in no time flat. They do recommend clearing a limited area where there are safety issues. Around heaters and cooking appliances, walkways and entry points and suchlike.
-They do recommend that workers be carefully selected to be empathetic and be able to keep a cheerful demeanour while working with the hoarder client. Basically, to support them while getting them through the attachment-to-junk problem. So if you've got a helpful friend (or forum thread :D) available to encourage and support without judging, yay!
-Collecting is not hoarding. Collecting has a purpose and sense of order about it. (My collections have purpose... I'm falling down somewhat on the ordered aspect. That I need to deal with!)
-People with a hoarding problem have a reduced ability to distinguish between what has and hasn't got value. (I saw my Dad slipping into this a bit as his dementia got worse. He's always been a stamp collector, including special edition pre-stamped envelopes, but he started carefully collecting every envelope that came his way. Mind you, he did keep them very orderly....)
So yeah... to some degree, I have to admit to a hoarding problem myself. I'm still pretty sure it's because I'm emotionally and mentally overwhelmed, and that state of being overwhelmed reduces the mental energy I have available for sorting and decision making.
Regardless of the why, it's something I need to deal with. I can't see much changing on the "mental space" front any time in the near future, but I need to find some way forward despite that. I know when I have access to a space where I have more control, I do tend to set up that space in an orderly way. Mess is in so many ways "not me", but still I find myself surrounded by it.
Like I said, a bit confronting. But with some helpful challenge in the mix too.
