Grief shared is grief diminished -
I'm glad I found this article! Grief is a true equalizer and people who never met, and whose lives could not be more dissimilar all experience this spiral of overwhelming emotion.. Human beings are truely unbelievable!
I think the stages you so cleverly described are all true - and I agree in terms of the timeline..
I'd add to that that there is a certain spiraling which goes on and these stages intertwine, and that's where we all differ. Though each of the stages dominates at some point (and in terms of ordering and time that those take I do agree with you)the other ones are present as well and they ultimately bring you back to your base. That is you may be 'creating your healing' in your 'cave woman' period but if the time's not right back you go to being the 'cave woman' you really are.
It's the hardest journey you could ever take - mostly because you have lost your entitlement to be happy and to enjoy everything along the way...
Once you really deep down in your heart can believe that it's Ok to be happy - therein lies your foundation for a new normal.
