When loved ones go, the world shifts in a strange way so everything feels slightly wrong.It just seems so surreal that dear Sharon has gone. Even though I was expecting this, it doesn't seem right. Sharon was only 58. X
I think you hit the nail on the head, calling it surreal.
For me it feels like it takes time to get used to and settle into this slightly changed world before the world feels normal again. I guess it's a normal aspect of grief, it happened every time I lost someone close, including my dog.
