We lost everything

We lost everything today in a house fire. The biggest loss is that of my mom's boyfriend's mother, her dog and our beloved cats. The house is a total loss and we are left with just the clothes on our backs. This is a total shock for all of us and we don't know where to start. If anyone out there is able to help we'd be eternally grateful. All I can say is that thank god we have each other. In my heart i have to believe that this too shall pass.
