How do you deal with your Mother's cancer and closeness to death?

Thank you for your encouragement and confirmation to trust the Lord through the whole thing. He does help dealing with all aspects of an illeness, loss, grief, etc.

Thank you for responding! How do you just be there for someone? I'm not sure how to be there for her. Right now, she is still capable of doing things for herself, but I don't know if she really needs help or not until after I see her health set back. I can't tell her not to do things, because she wants to live no matter what. This is a really bizarre feeling to feel. I feel helpless just watching her health diminish in front of my eyes. I try to spend as much time with her that I can and keeping spirits lifted and happy. My heart is just crushing inside knowing this may be the last memories and times together. I guess I'm doing all I can do for now. I call her everyday and sometimes a few times throughout the days. I met her for lunch today in between her chemo treatments and lungs being drained. My father is with her and I know she needs and wants him by her side and of course he wants the same. What do I do without just being in the way or being a downer to them both? I try to encourage them with the Word, prayer, and just being around and noticing things that need to be done. I guess that's all I can do... If you have any more suggestions, please share. Thanks
