Thanks for the link to this interesting article. It seems as though this is all about people who are grieving someone who died. But there are other reasons for long-term grief as well. I feel as though I've been grieving for over 4 decades. It's my own fault. I stupidly caused the problem to begin with. (Too late to do anything about any of it now.) And I really never did anything to try to resolve it. But then realistically for much of that time there weren't mental health services available that would have been of help either. So now to the greatest extent possible, and in my own way, I'm one of those long-term grievers who have permanently withdrawn from society. And, yes, I wear a lot of black.
