Grandma70s - I think the OP probably meant bereavement in the way you describe it. Both my husband and mother died in their 50s after distressing illnesses. It was a relief though I obviously was sad and now feel I missed many years with both of them.
My father was elderly, frail and very disabled from a stroke. I felt he had had a good life and lived to a good age so did not grieve in the same way as with younger people.
My best friend from school days died in her 60s. Though we kept in touch, we were no longer close, but I was devastated. I can't explain why that death upset me more than others, and still does.
What time do you get up and go to bed?
