My grandad won't accept my nan is dying ???

My nan has blood cancer, she got diagnosed 3 months ago. It's incurable and that's a fact.

She has weekly blood transfusions due to her haemoglobin levels dropping also.

My nans very sick and my grandad is in-denial!!

My nan spoke to her mental health worker today and explained how she feels about her having cancer and dying.

My grandad went mad and said "I'm so sick of nan telling everyone she's got cancer and she is dying, the doctors said they can manage it and she will get better'

Actually the doctors said the complete opposite I was there myself with my grandparents and my mum. My mums a nurse she understands a lot!! They said up to two years but depends how aggressive it'll be. The treatment such as injections will only slow it down.

Why is my grandad being like this it's so sad :( how can he not see his wife is very sick!!!
