Time does heal a lot of wounds. The farther I get from certain dates, the hurt eases a little. The grief counselor for my support group often describes it as a "shift". Emotions can change and change again like a wave. Sometimes the wave is far away from you, sometimes it just covers your toes, and sometimes it washes over. But it never leaves. You just have to figure out ways to handle the emotions when they wash over.
I will never get over my losses. And I am not alone in that. I've heard from many, many women, several much older than I, who have gone on after losses to have many children. And they still think about their miscarriages. They still think about their losses. They still miss them and wonder what their babies would have been like. They all have moved forward though and I will too.
Do your loved ones a favor- Never tell them that they should be over a loss. It's just not going to happen.
