Wow, Keith. I'm so sorry for your loss and that you had this experience in the US. For the most part, I've found that people have been wonderful and supportive here in my corner of NY. That said, I've heard all the platitudes (e.g., she's in a better place, she wouldn't want you to be sad, etc. etc.) which used to really upset me. This is a huge reason I write about grief. I just...want to clarify it somehow, but I also want other grieving parents to know that they're not alone in this dark, endless place of parental grief.
As for the platitudes, I've come to believe that people truly don't understand this kind of grief unless they've experienced it. I know I didn't. That one really awful comment I received was an outlier (thank goodness). I hope you find some support and peace from your move.
