This post hits close to home for me. I lost my mom in November, too (Nov 30 - I have been off the forum until just today...). It was sudden and not sudden, she was only 72 but both of my grandparents on her side also passed around that age. Mom had COPD and severe heart failure (I knew about the COPD but was not aware of the heart problems). I was with her in her last week; she was in the ICU and they unfortunately could do nothing for her to repair the heart damage. I am heartbroken but grateful for the time with her and grateful that she passed peacefully in the way that she decided. As the end was nearing she changed her "full code" order to "no CPR/no intubation" the day before she passed, and after that was finished she said she was "ready to go to heaven and rest".
She had a very small estate without a will. It will be tricky to do a few things to wrap it up (because there is no will, there is no "executor" paperwork so somehow I need to get the legal authority to close out her small bank account and forward her mail to me to pay final bills). My siblings were there with me to go through her small apartment and revisit the letters, photos, and cards she saved from us over the years (she saved every single letter...amazing). It was a comforting way for us to get closure. If there is any kind of inheritance it will be very small, less than $1000 split three ways. I am the oldest sibling and the only one without kids or a job so I don't mind taking on the responsibility -- it's an honor to help in this way.
Jerry I'm so sorry for your and your DW's loss. And also sorry Pb4uski for the loss of your mom. Hopefully you have many years of good memories to treasure.
