Trying to find a new road

My grandmother just died, we were extremely close but in the end I didn't show it, i loved her so much, she taught me to be who i am today, the strong, independent , and bold woman i am today. I, however want to get over the death when my mother just keeps bringing it up. She is obsessed with my grandmother's death...buying books on death, and always bringing her up, she even repainted our living room because grandma picked out a different color before she died " it was a tribute to her." I'm just so tired of hearing about it, i dont deal well with death and i would like to find a new road, a new path for myself, one that does not include thinking about her death everyday and reminding me that i wasnt as helpful to her as she was to me in the end.
