can't get the last days of my dads life out of my head

I feel lost when I think about my dads last days in the hospital before he died.
I spoke to him, I read to him, I sang to him which are all nice memories but I still feel I gave up on him by signing a DNR for him.
I can’t get past it.

Shana sounds like you were there for ur dad when he needed you. Obviously you wouldn’t have been offered the dnr if the medical staff felt there was any other option. I often think of my dads last day in hospital and take great comfort in knowing that he’s not suffering anymore. I hope you can get past this as grief is difficult at best of times.
