Hi E. - I know you are so incredibly worried about your mom. Remember that you dont have to go this alone. Pull in your husband, other family members and your mom's friends to help carry the load. Find a friend who is willing to let you vent and cry all you want. You need an outlet outside of your husband and your family to help you cope with this.
Think about some practical things to help make your mom's day to day life easier. No matter how much chemo and radiation she has to do, she is going to feel really tired and nauseous but it's important that she maintain good nutrition. She will probably appreciate simple things like having fruit juice popsicles on hand when she feels sick but needs to keep up her energy. Some chemo drugs are taken orally and are fruit-punch flavored so keep that in mind when purchasing juices and drinks, etc. There are going to be other tastes and smells that send her through the roof so think very simple and easy to digest foods. She will also want to avoid any type of soy because of the estrogens.
She is also going to be very sore for a while if she had a mastectomy and has reconstruction devices implanted. Perhaps pull in one of her friends and you all can pull out some things from her kitchen so she will have easy access and wont have to reach or lift anything remotely heavy or pull in friends to help with household chores like vacuuming, bathrooms and laundry, etc.
One of the most important ways to encourage your mom during this time is to pray for her and with her. There is no better time than this to seek out God's help.
My oldest sister is a cancer survivor and she just passed her 13 year mark since her last treatment. I wish your mom a quick and lasting recovery.
Blessings,
