People Die! We all know this, so then why is it so hard when it happens?

My grandma passed away from cancer September 20th 2014 at exactly 7pm, my three aunts, my mother and I were all by the hospice bed and accompanied her through her last breaths...she had had uterine cancer years before, she had it removed and went though all the check ups needed, every time she came up fine, and all of a sudden she was told she had cancer and it had spread thru all the organs, a month and a half-two months she passed away. the last couple of days she spent them at a hospice, she couldn't eat, talk, move, (she said a couple of words, fixed her hair, held my hand, and touched my face here and there). her sister, 4 daughters (one of them my mother) and I all stayed in her room 24/7...and it is sad but we actually felt releaved once she passed, this meant she no longer felt pain, no longer felt her body burn from the inside out, she was no longer frustrated because she just wanted to die already; she has no found peace...we spread her ashes in a beach in Maui where she lived her last year or so and I kept her urn and a lock of her hair.
Anyway, this is the last picture or so I took with her (while still alive) I obviously didn't take a picture of her face out of respect (she was a huge diva)
I wish she could hold my hand again...
