How do you get over it?

How do you ever get over losing a child? Is it ever going to be possible to live one day without thinking about him? He would have been about a week old today. I would have been a mom of three. I see families with three kids and it hurts.
His gravestone was laid out sometime this week. I went to the cemetery yesterday and there it was all shiny compared to the weather-beaten stones surrounding his.
I try to think of what people who have lost babies in worst scenarios than mine tell me--God doesn't take healthy babies. That helps for awhile, but I still miss him.
Rest in peace my Luke. I'm always thinking of you. I can't wait until I can hold you again.

Love,
Mom
