I've lost my grandmother and grandfather recently, it's a painful experience to go through but we all get through it. The pain you feel is from having years of having a wonderful loving grandmother and amazing experiences with her. So what I am saying is that hurting isn't a bad thing, it just means the more it hurts, the more you really love her. The pain of loss sucks but if you think of it, it is much better to have loved and lost than not to have known her at all. It is painful now but in time you will look back at all the wonderful memories you had with your grandmother. Spend as much time as you can with her, having family around to support her through these hard times will help her a lot.
I remember when my grandmother was diagnosed with terminal cancer and they told her she had 2 months to live, she thought her life was over and just had no more will to live. I made her a card with photoshop saying how much I love her and wishing her to get well. She never saw this side of me, how caring I really was and it gave her reason to want to live, that she had family that loves her and didn't want to lose her. She lived well over a year after they had given her 2 months, I believe the support of her loved ones helped with her prolonged life and she got to enjoy her last year with us.
What I am trying to say is don't lose hope and be there to support her whenever you can because that support can greatly help her mentally and with a better mental state comes better health. I wish you both well and hope she can get better.
Here are some virtual hugs
