Gwenivere....very well said.
The months of the year and whatever significant days they include for any of us, now become triggers for grief to occur or return. For myself, I have decided to ignore any sort of holidays anymore. Just too painful...
I go very low key and just do the absolute minimum or do nothing. No pressure is a good thing.
Everyone is different. I have no family or social support anymore, so I have to do what's best as a solo.
