One of the difficulties with grief research is that it risks making certain kinds of grief seem normal and others abnormal - and of course having a sense of the contours of grief is, I think, truly useful, one has to remember it's not a science, it's an individual reckoning, which science is just trying to help us describe.

Yet the story of Orpheus, it occurs to me, is not just about the desire of the living to resuscitate the dead but about the ways in which the dead drag us along into their shadowy realm because we cannot let them go. So we follow them into the Underworld, descending, descending, until one day we turn and make our way back.

Nothing prepared me for the loss of my mother. Even knowing that she would die did not prepare me.

Grief is a bad moon, a sleeper wave. It's like having an inner combatant, a saboteur who, at the slightest change in the sunlight, or at the first notes of a jingle for a dog food commercial, will flick the memory switch, bringing tears to your eyes.

I live to collect information, and I am also a perfectionist.

It's a blessing not to be alone in your grief but it's also painful to see your parents and siblings in pain.

I wasn't prepared for the fact that grief is so unpredictable. It wasn't just sadness, and it wasn't linear. Somehow I'd thought that the first days would be the worst and then it would get steadily better - like getting over the flu. That's not how it was.
