How do I help my mom when she loses her mom

My grandmother is dying. My mom is taking it HARD, can barely function when it gets bad. It’s okay now, she was down for a few days and it was scary but she has a VERY good doctor that cares a lot about her and today she has a light in her eyes that I haven’t seen in a while.

But the facts are, my grandmother has cancer, is refusing treatment and is dying. She would rather have quality of life over quantity. We don’t know how long she has. Before I continue and come of harsh..

My views on death are basically this.

My grandmother is not ceasing to exist to me. I had a heart to heart with her about her death, and how I believe she has the right to choose her death and wasn’t angry with her and that it’s okay to die, and I told her I was jealous that she would be with her mom (my nana) sooner than the rest of us. I am not taking this bad, I am at peace with this. But this is my moms mother. And sometimes she looks at me like I.. uh?

Kindof like i don’t care or something, I care. The thought of my grandma no longer being here hits me and I don’t want that to ever come. But it will and that’s just reality.

I guess I’m just trying to figure out how to navigate supporting my mom who is heart broken without offending her by the way I feel about this situation. Any advice would be appreciated

I just also want to add that I do not think the way my mother is handling this is wrong. It’s not wrong, it’s just her way. We all have our own
