And being home with your mom and family and dealing with your emotions and stress of other people's emotions may be a lot easier while not eating. However, you may become more of a target during that time, and so may find yourself focusing more on what you are doing than why you came home. I have been through losing both parents to cancer, and I am sending your mother - in the general area of North Canada - some love and healing light and prayers.
I also humbly suggest you might check out the iodine supplementation board. Breast cancer responds to the simple addition of elemental iodine to the diet in dramatic healing ways.
Best,
