My heart is breaking

Just talked to my daughter. She is terrified!!! She doesn't want my son to take her daughter because she is afraid she will never see her again. She said to me "What if something happens and I die? Olivia is too far away from me. I want to try and keep her with me, because everyday I look at her it will give me motivation." I truly understand how she feels but having been through chemo and radiation myself I'm just not sure she will feel like taking care of her. I think after I get my gallbladder removed Friday the 24th I may go and stay with her for a little bit. I'm just afraid because I have a hand that doesn't function well, so I'm a little nervous about picking up my granddaughter. But I really believe she is going to have a hard time taking care of her daughter while going through treatment. I keep thinking this isn't real. But it is, and it's something that my boys and I have to face. My younger son is really not handling this well at all. Lately there is so much "CANCER". Either someone has it or someone is being tested for it, or someone is dying from it. I really hate that word anymore. I hated it when I was diagnosed with it but I have to say I hate it more now.
