Replacing things lost in a house fire

We were finishing up moving into our new house (we had two or three days left of really kicking butt to get things done) when the unthinkable happened. Someone set our house on fire. It was a total loss. There is only hazard insurance on it, and even if they so pay out anything, it will be to my mom (the mortgage was in her name at that house) and she has things to replace, too. I lost baby photos, keepsakes; things that can never, ever be replaced. But I lost things that CAN be replaced. Except I can't afford to do so. All of my money goes to pay for the new house payment (I can't even pay all of THAT, the friend I'm buying from is covering $170 every month until I can manage) and bills. I am overwhelmed with the loss and devastation, and while I know that I should be thankful for what we DO have -and I am, believe me- I can't stop feeling helpless about not being able to replace the replaceable things. Both of my kids lost clothing, toys, books, etc. as did I and my fiancé. We lost household things (pots/pans, dining room chairs, etc.) and so much more I am very literally in years every time I even start to think about it. It took me years of working to get some of the stuff we lost, and being that I'm in school full time and home as much as I'm able to be because of my son who is on the autism spectrum (& has been having real problems the past couple years) I can't even begin to think how I can do this without asking for help. So I am. Please. I can't do this by myself, and I am strong enough to know that sometimes we need to know enough to ask others for help, even when it seems hopeless to me. Please forgive any typos - I'm just a wreck.
