Carol, I guess you will not want to hear this right now but as devastating as that last day must have been for you, there will perhaps be a time in the future when you will be able to look back and thank God that Eric stayed with you at home on the kitchen floor for those few hours. If the day had unfolded slightly differently, if he hadn't just seen the GP that morning, the paramedics might have been obliged to take him to the hospital and your beloved Eric might have been subjected to a post mortem.
Cold comfort right now, I know, but I really believe that there are times when the human spirit can control destiny. Imagine Eric, so poorly, so breathless, but with enough strength to get home from the doctors and then once he was safe with you, allowing himself to let go.
My friend who is the chief exec of a hospice says there are those to hang on and on for a special visitor or an important date / anniversary and then slip away, while there are others who seem not to want to die in front of people and find the strength to wait for the moment when the family slips out for a break. I am so sad for you that Eric has been taken away so suddenly and in such traumatic circumstances but how wonderful to think of him being at home, his heart just knowing that he was safe in your arms and your voice being the last one he heard.
You are in my thoughts xxx
