That is so sad, Primrose; I know the pandemic made everything more difficult.
Not bereavement as such, but one of the best series of meetings I went to in another church, not my own, was a kind of preparation for our older years. It was not intended for those about to retire, but a bit further down the road, covering things like finances: Pension Credit, Attendance Allowance, Equity release, the cost of care, funeral plans; and legal stuff like making a will, PoA. Health, diet, well- being, social life, spiritual support etc. It was very well done, with knowledgeable speakers.
I dipped my toe into a bereavement group at another church. I am not sure I want to go again, as although it is good to talk on a one-to-one basis, I prefer to be amongst groups of people where bereavement is not the main focus.
There is nothing specific at my own church. Our priest is lovely and led a beautiful burial service for my DH but she has a really heavy workload and does not have the time for extended or extensive support. We don’t seem to have a team to share the workload.
