> There’s no modern cultural framework for dealing with death.

Indeed. We used to have religion to help us deal with it. In our modern world driven by science, death is just the absence of life. Since all (physical, chemical) reactions have ceased, science has nothing more to say about it. In trying to deal with the ills of organized religion, we may have also disposed of its benefits.

Very sorry for your loss.

Science has also given us time machine surrogates - photos and videos. I understand this doesn’t work for everyone and can sometimes make things harder, but for me, seeing our common past brings back the smile to my face.
