I am so sorry for your loss. My mom is a uterine cancer survivor, but another close friend is fighting it right now. She is in her 40's and has a unique form of it too. This makes me worry for her even more. Keeping you and her family in my thoughts.
Someone rec'ed a book to me after my sister died called "I Wasn't Ready to Say Goodbye" and it helped me deal with some of my feelings after her death.
Thank you for all of your care and concern. Last night and this morning have been really tough, but your words mean so much to me. Ali, I am definitely going to check out the book you mentioned.
