I remember when my father died, he had a stroke 6 months before, suffered pneumonia, several heart attacks, was paralysed down one side and was as stubborn in death as in life, he really fought to stay on. But, it was the best for him really, no more pain, no more muddled reality, no more constant care and being reminded of his paralysis.
He looked so peaceful afterwards despite dying in pain. We all gathered around his body and the gallows humour came out. We were very respectful of him and also fearful when we were young and there was this guy we could take the Mick out of and he couldn't do a thing. It was part of our grieving process. I had to explain to a taxi driver last week that I probably won't collect my pension, that life is more finite for MM sufferers than for others, I would have thought your father would have known that as well, so let the grieving process continue, remember the good times – and the bad for that is what made the person he was to you.
