My mum died of bone boe cancer on the mothers day 2015. She had a fall and was taken to hospital and thats when she found out. She kept it from me for a while but i found out at the end of feb 2015. 

I had moved out with my wife who was disabled from a brain injury in 2010. I was taking my mum to hospital appointments but stoped in 2013 as my wife had alot of hospital appiintments at that time. 

I feel that if i had taken my mum to her appointments she would still be here. Am i wrong for thinking this?
