I found this article really helpful, too, Marion. When my dad died (sudden massive heart-attack) many years ago, I really felt I'd never be able to function again. Reading the article was painful, even after all these years, as I recognised many of the feelings described as feelings I'd experienced at the time.
It was good to read this article & see how far, far, far I've come. I hope no future loss will debilitate me that way again - & I don't believe it will.
Thanks for posting the link
