I have seen lots of threads on MN for partners of hoarders, but (apologies if I am just unobservant) haven't noticed any for those struggling with their own hoarding tendencies (as opposed to general clutter/messiness, which I'm sure you'll agree is very different from hoarding).
No judging, no "Just throw it away!", just support, understanding and chat about our difficulties - whether or not you are ready/willing to confront them. :)
