I find this a strange question. I don't relate to any of those stages and don't think they are applicable to something like a pandemic. As someone else has already said, the research for those grief stages was done on terminally ill patients coming to terms with their own death.
The pandemic is just one of those things. I'm in my 60s and so have seen various problems in life, a pandemic is something that occurs from time to time in the human race. My mother lived through the 2nd world war, she suffered far more from that, than I have living through a pandemic. My grandparents lived through the 1st world war and the flu' pandemic, in harsher times than ours today.
Yes, COVID completely messed up my own plans so that I had to return to the UK rather than staying overseas as planned. I got COVID in the first round when I returned, it was a nasty 3 weeks, but I feel remarkably lucky to have survived. I know others (past colleagues, a distant family member etc.) who have died. Of course it's sad but they were older and already in ill health and would have died of something eventually anyway.
I was not working during lockdown but received furlough pay....many didn't, I count myself extremely lucky to live in a country that provided this. I have received vaccinations (and now a booster) early on and feel very fortunate indeed to be in a country which offers this.
All in all, no, there is no grief. It hasn't really been that hard for me, I'm happy with my own company and seen friends and family as soon as the lockdowns eased. I've even changed jobs this year, which has been good, and I feel happy (and safe) with the healthcare provision we have with the NHS. So I'm not at any "stage" of grief and never have been.
As I said at the start, weird question.....
