This must be absolutely horrible for all of you. As you can't go back to what was, the only way to look at all of this is as a new opportunity to begin again. What you lost is memories and stuff. The memories won't leave and the stuff can be replaced. Yes this will be difficult but you will have family and friends to help. Life isn't always smooth but a positive attitude will help you get through this rough patch. Enlist all the help you can and good luck with all of this.
