Sgt Mickey...
I understand!!!!
But, if you are really the only one who is struggling with this, I would almost tell you that , yes, you are a hoarder. This stems from the inability to distinguish real/true value from sentimental value... Or, quite simply, the inability to guage 'value'.... For instance, old papers and receipts from 20 years ago are perceived to be very valuable and/or important. When, of course, they are not.
My advice from the other side....
My MIL was a hoarder...
It was a problem.... And has also been a problem because my DH has picked up on this. It has been a battle for me to maintain our small home. From the very beginning, when we were married, boxes of stuff from his parents place, from decades ago, ended up at my house. To this day, our spare room is locked away, wasted space, because it is 3-4 feet high with 'STUFF'. (granted, some of this not just junk.... but still.)
To the day she died, my MIL refused to organize, clear out, sell, or donate anything...... When she passed away, THIS was the nightmare that she left to her son. My husband spent days and weeks on end.... dealing with all of this. I had mentioned to get a rental dumpster... and finally that is just what he decided to do. When they delivered the dumpster, they were short on the smaller ones, and said, hey, for the same rental, take this huge one. IT WAS FILLED UP TO OVERFLOWING.... TOTAL JUNK.... out of a regular sized, smaller, 3 br one level house. It was almost unbelievable.
Just from the stuff that DH brought home, as it might be stuff to garage sale, donate, or keep.... I could barely park our vehicle in our garage.
My DH grew up on their 'farm'.... 50 acres, barns and outbuildings, two level house with basement....... The thing is, the amount of living and storage space really has no bearing on this issue.
