(((hugs))) I'm so happy that no one was hurt!!
When I was a teenager, our house burned into rubble. It is a traumatic experience, but the most important thing is that everyone made it out alive. Our memories cannot be stolen from a fire.
You might want to ask friends & relatives to go through their pictures (from years ago) and gather some pictures for your mom, so she can build some albums again.
I learned a very important lesson because of that fire. Caring, love & generosity are not found just around Christmas time. I hope your are as overwhelmed with well wishes and help as we were.
I love Claudia1's suggestion of keeping a notebook.
If you'd like to PM me, feel free.
(((hugs))) & prayers
