I was with my husband when he died at home. For the longest time, every time I thought of him, it was in those final moments.
Over time, I learned how to "redirect" my thoughts to happier memories, but it takes a real effort. I put pictures of my husband close by so I could focus on the positive; having that visual reminder really helped me. If you are lucky enough to have children or grandchildren, they are a great source of happy memories because that is what they remember. It is true that in the beginning you are preoccupied with the details of death and it can be very overwhelming and all-consuming. This is where I learned the "art of compartmentalizing", a big term for breaking it down into more manageable pieces and having the ability to "switch gears" and do something else.
You don't have to do everything at once. Take a break: go for a walk, call a friend, pick some flowers, or read until you feel ready go back to the tasks at hand. Give yourself time to do everything you need to, but limit the amount of time you spend doing it. Ask for help if you need it (this was a tough one for me). Time is a great healer, but it doesn't mean that I love or miss my husband any less because I am not thinking about him 24/7, and though I do have my "grief attacks", I am able to think of him in a happier, more comforting way. And as always...remember to breathe and be gentle with yourself. Deb Edwards
