I wanted to write as soon as I read your post on your mom's passing, but I haven't been able to take the time. I'm so sorry for your loss. My mom was getting treated at MSKCC in Basking Ridge maybe right after your mom started getting treated in Manhattan. I always felt closeness in reading her posts because they sounded like my mom could have been writing them. She was such a kind and gracious person, and always had encouraging and candid responses for me when I asked her questions directly.
I know taking your mom to the appointments in the city couldn't have been easy (I did it just a few times procedures & meetings with the surgeon, and the drive -- not to mention the parking -- always felt like such an obstacle course), but I was glad for your mom that you were there to do that for her. My mom's in hospice now and may be joining your mom soon. I'll tell her to look for Mary.
My warmest thoughts are with you and your family.
