My mother also has cancer. I was so upset when I found out that she had cancer. Not my mom!!! I love her so much and didn't want her to leave. Now I have excepted it or at least dealing with it. My mother is worried about feeling pain and does not to leave her family. I am more supportive of her and reassure her that we will do everything possible that she is not in any pain. Have you talked to hospice? I know that they will be included when my mother and our family needs them. Just try to be there as much as you can and tell her often that you love her. Good-bye is a word that I would not say to her but instead "I will see you later." Talk to her about memories and surround her with family pictures. Just hold her hand and be there! I am so sorry that you are faced with your mother's illness and that you are so young! I am sure that others can help you too. You are in my thoughts and prayers!
