I often say it doesn't get easier, you just get used to it.
The devastating moments get further and further apart and you learn new and different coping strategies, but there are still moments that bring it all flooding back.
My daughter used to ask me to sing "You are my sunshine" over and over to her when she was in the hospital and after she relapsed. This morning at our youngest son's pre-school talent show he chose to sing that song and I lost it. Fortunately I don't think anyone but my wife noticed.
