Please help us extend the life of our mother

My mother was diagnosed with endometrial cancer last 2013 and had to undergo chemotherapy sessions. She was then ok and living a healthy life together with us, her children and her grandchildren. However, last December 2017, she became weak due to frequent bowel movement. At first, we thought it was just a diarrhea but turned out she had problems with her colon. She was brought to the hospital, and was diagnosed with stage IV. She is right now at Jose Reyes Memorial Medical Center and underwent kidney stent insertion, dialysis (3x a week) and chemotherapy. We are only 2 in the family both working as regular employees. As children, we would like to prolong our mother's life so we can show her how much we love her and how thankful we are for having her us our mother. That despite her lack of education, she tried her very best to raise us, provide us with everything and send us to school.
