Wendy,
My heartfelt sympathy to you and your entire family on the loss of your mom. No matter how old you are, you always want your mother. It has been too many years since I lost my mom (different disease), but I still miss her. I knew she was in a better place, but it is still difficult. I am sure she was very grateful and proud of how you helped and supported her during her courageous battle.
Take some time to remember her, but also take some time to take care of yourself too.
Laurie
