I think grief changes us permenantly. I was going to say, especially if it is an unexpected death. But on reflection, it's not fair to say that because grief is a very personal thing, and if it is someone you are very close to, a spouse, a parent, a child, the loss is like losing part of yourself that you can never regain. I have a brain-injured son, who is still alive, but he isn't the same person that he was. It took me a long time to allow myself to grieve for the son I lost. Now I have a different son.. I love him deeply. I wrote a book about him. But I also miss the son I lost.
