In my personal experience, my body did not allow me to delay or put off. The feelings were too enormous to ignore or suppress. The only choice I had was to keep myself in a private place much of the time in order to feel uninhibited.
The very early hullabaloo and the sequence of events, once I got the news, was distracting and enabled me to get through whatever services and ceremonies I deemed appropriate. In my case, that was only several days of hyperbolic activity, close family, noise, confusion, food and being out-of-body.
I still deal with the grief, 16 years later, only less often, but at surprising times and places. A smell in the air can trigger it as can the sight or sound of a red-tailed hawk soaring and screaming.
“Handling grief well” is really a meaningless expression. Some would define that as rending of garments, gnashing of teeth and ululating at top volume. Others would not. Kubler-Ross’s list is not written in stone. It is a guideline only and should not be used as a checklist.
The only issue, really, is allowing yourself to feel what you are feeling The rest is distracting verbiage.
