I am the mother of a child who died. And that makes Mother's Day very hard.

Recently I was talking to a mother whose child had just died. "What about Mother's Day?" she asked, through tears. It was hard to know what to say, because it's a terrible day for those of us who have lost a child. Other days of the year you can maybe make it a few hours without thinking about your loss; other days of the year you can pretend that you are an ordinary person and that life is normal. But not on Mother's Day.

On Mother's Day it's in your face that your child is gone forever. On Mother's Day you can't pretend you are ordinary or that life is normal. All the hoopla, all the Hallmark hype, the handmade cards and flowers and family gatherings, make it almost excruciating.

Our town has a Mother's Day road race for which I am eternally grateful -- especially because, in a demonstration of grace's existence, the start and finish are next to the cemetery where my son is buried. On my way I can visit his grave and say what I need to say and look yet again at the name we chose for him carved into stone. At the end of the race, they give all the mothers a flower; on my way home, I go back to the grave and lay my flower there. And then I move forward with the day.

See, that's the real challenge after losing a child: moving forward. It's almost impossible to envision in that moment of loss; how can life continue after something so horrible? But life does continue, whether we like it or not. There are chores to do and bills to pay; morning comes, again and again. So you pick yourself up and you live, but you are never the same.

At first, we are different because of our raw sadness. But over time, the sadness moves from our skin into our bones. It becomes less visible, but no less who we are. It changes into a wisdom, one we'd give up in a heartbeat to have our child back. We who have lost children understand life's fragility and beauty. We who have lost children understand that so many things just aren't important. All that is important is those we love. All that is important is each other. Nothing else.

It can feel very lonely, being the parent of a child who died. Especially on Mother's Day or Father's Day. We feel so different from those around us, all those happy people with children the same age our child was, or would have been. But over the years, I've come to understand that I'm not alone at all.

There is a wonderful Buddhist story about a woman whose son gets sick and dies. She goes to the Buddha to ask him to bring her son back to life; I will, he says, if you bring me some mustard seed from the home of a family that has not known loss. She goes from house to house but can find no family that has not lost someone dear to them. She buries her son and goes to the Buddha and says: I understand now.

That is what I understand now. It doesn't make me miss my son any less, or Mother's Day any easier. But it helps me make sense of it; loss is part of life. There are no guarantees, ever. Our children, and all those we love, are gifts to us for however long we have them.

I understand now too that we are together in this, all of us, in joy and in loss. It's the connections we make with each other that matter -- it's the connections we make that give life value and help us face each morning. As G.K. Chesterton wrote, "We are all in the same boat in a stormy sea, and we owe each other a terrible loyalty."

Years ago, I chose words to say each time I go to my son's grave. It makes it easier to have a ritual. And over the years, the words have come to mean more to me. They aren't just about about grief anymore. They are about who I am, what I have learned, and what I can give.

"I will always love you, " I say. "And I will always be your mother."
