I am so sorry. I understand how this feels. My DM died, unexpectedly, on 16 July. I shall never, ever forget the sense of pain and desolation I felt, sitting in her sitting room beside my dad with us taking it in turns to phone people. She was greatly loved and, like you, I encountered lots of tears. I still don’t know how’d we did it. And having to tell my children, who all adored her, was painful beyond words.
Those feelings of wanting to tell the very person who you can’t tell are also very painful.
I’m 3 months on now. The outright shock of those first few days has abated. But the pain is still pretty raw really. Taking day at a time really does seem to help.
Everyone is different, but for me the planning and carrying out if the funeral just so brought me great comfort. There were some little touches (certain things to put in the coffin with her), the readings and music at the service, particular flowers, even serving her favourite drink at the wake that I am pleased we did.
I have also found setting up an on-line memorial for her quite cathartic too.
I hope you find peace and comfort. I am so glad you have support.
