You may have to work hard and fast to help your mother. One option is to see if there is a Cancer Treatment Center of America near you. They have one in Illinois and a few othere states. They do pay for transportation and lodging for a patient and a caretaker. I do not know much about them, other than they will work with you from all aspects:physical, emotional, spiritual. They use conventional trt. along with supplemental to help boost the immune system. I like this approach. You may find out more about them by doing a search online.
When my sister went through this with her daughters, she lived like she would stay here but planned like she may leave. As she went through trt.. she eventually could not work but had enough energy some days to sort pictures, write notes, and organize paper work. The notes show so much insight for her children and husband no matter what their age when they read them.
It is a difficult balance to allow the emotions to show and yet to be practical in what has to be done. Talk to your mother and ask her what her priorities in the coming day, month, year, years are. Use that as a guide to help her accomplish them. Some days it will be to just fight the ugly beast of cancer. Other days you may have fun taping her doing things with you and others you love. If we only did things that way all the time, most families would be much stronger. Your conversations may go from crying to laughter to hugs to silence. You will cherish every minute as you decide the path that is to be taken.
God bless you and your mother.
