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.

While I did a lot of research, I ended up feeling that the best way to write about grief was to describe it from the inside out - the show the strange intensities that come along with it, the peculiar thoughts, the longing for that past - all the strange moments of thinking you glimpse the dead person on the street, or in your dreams.

A mother is beyond any notion of a beginning. That's what makes her a mother.

One word I had throughout the first year and a half of my mother's death was 'unmoored.' I felt that I had no anchor, that I had no home in the world.

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.

Relationships take up energy; letting go of them, psychiatrists theorize, entails mental work. When you lose someone you were close to, you have to reassess your picture of the world and your place in it. The more your identity was wrapped up with the deceased, the more difficult the loss.

One of the things about grief is that it can bring a deeper perspective into your life; in the end, it has, for me, though it's also brought sorrow.
