I lost my Dad in March, complications from a biopsy.
My brother and I were with him, there was no reason to try and delay the inevitable, his body was shutting down anyway. It was very peaceful, and given that the staff were telling us it was certain he had advanced cancer, then his passing probably saved him from further suffering.
So to me, I'm heartbroken at losing Dad, but relieved he wasn't in any further pain.
I simply can't understand the mum's desire to try and keep her son here.
