Belongings lost in a house fire

I hate to make this, but recently (less than two weeks ago), my friend and I moved into a house we were renting. Sometime today around 2AM the house next door caught on fire and jumped over to ours. I lost all of my belongings- my laptop, desktop computer, clothes, guitar, all of the new furniture I got, my birth certificate, typewriter, books, groceries, etc. My cat, roommate, and I were luckily not there at the time and are all safe and sound, but the house is inhabitable, and I am in need of a lot of the things I lost. I unfortunately had not signed up for renters insurance in time. :(

I’d really appreciate any help, even if it’s just sharing this. Thanks
