In the 80s my wife and I were like that woman to a smaller degree. Our storage locker was full, and the second one we rented for overflow was also full. Then we started placing boxes in strategic corners in our own living room and bedroom. Finally I took a one day course at the Learning Annex on how to stop being a pack rat. The rule to live by, if you havent touched it in six months store it. If you havent taken it out of storage in two years, sell it or give it away to family or charity. If noone else wants it -- throw it away. Exceptions are items that actually are conventionally worth something - like heirloom jewellery, working appliances, undamaged art and antique furniture and collectables and so on.
