Same as what Brad said, don't know what else to say.
The house that I now live in was burned down when I was building it in 1987. Fortunately, we had not moved in yet, and it was still devastating. It was arson, on St Patrick's Day, some teens getting out of hand broke in, partied, and burned it.
Some people say it is just material things that you lost, and don't worry about it, but they are wrong. It is your time and effort, the piece of your life that you put into it that is taken, so it hurts. Best of luck recovering from this terrible event.
