Bless you @JeanSheila
(Jean was actually my mum's name)
I'm afraid I don't have any answers or any quick fix or anything that will truly help you.
It's the oldest cliché in the book but it's taken lots of time for me to work through the stages of grief. And I'm still a sobbing mess on occasion.
Do you have support? A partner / siblings / DC?
I found my children a godsend. They were all young so still needed me and didn't really understand so I still had to take care of them. I didn't "fall apart" as I couldn't if that makes sense?
The early days were all about distraction, putting one foot in front of the other and dealing with all the shit that a sudden death throws up.
There was a lot of "fake it until you make it". Pretending to be okay did kind of help in some weird way.
I also went back to work after a week (my mum died on a Monday and I was back the following Monday, totally my choice but I was WFH and part time so was able to manage. Again It was good distraction!)
I kept things as close to normal as I could for the kids but I drank a lot of wine after they went to bed and cried a lot.
All that truly helped though was time. And eventually I have been able to focus on the happier memories and not that life altering September day in 2020.
Have you considered some bereavement counselling? I didn't but it's been so helpful for some people.
My heart goes out to you. Keep as well as you can ❤️
