I can't emphasize enough how much the videos I had of Rush helped after his passing. They've helped with other family members as well. Of course, you sit there blubbering like an idiot and wishing you could have had more of those moments, but they will always be there for you to view when you're missing your loved ones. The happy memories and images can do alot to replace the awful images of their last moments. It can help you remember that their lives were filled with many, many wonderful moments and the end was just a small sliver of that. If you don't have a video, borrow one from a friend, neighbor, or some places even rent them. It's the best investment you'll ever make!
Hugs to everyone who's grieving!
