I sympethize entirely. For the past 10 years or so it seemed every visit to my mom was filled with going through stuff, and her showing me where important things were, such as her insurance information and the key to her safe deposit box. I appreciated that she was trying to prepare me for the end of her life, but when it finally did come, it still took 3 people a week to go through her house and throw away things as well as make a pile of the things to be saved and shipped elsewhere. That was before the estate sale company came in and took care of the rest. It's a wrenching job, and although I saved a lot, I know there were things that were hard to toss - photographs of ancient relatives with no designation as to who they were, my father's Ph.D thesis, my long-dead brother's college diploma. Losing a parent is difficult enough and when one person is primarily responsible for their effects, it's really emotionally challenging.

Hugs to you as you proceed with it all.
