Stay at home mom got dumped

I have been 12 years with this man, 7 years as a stay at home mom, taking care of everyone. He decided to call it quits by videocall in the country where is currently deployed. I don't know what am I supposed to do, I feel lost, my life crumbling  because I don't know what will happen of me. No job for years, away from family in another province. All the things I accumulated over the years, for a comforting home to have for everyone, the reality of abandonning them, selling them is high since I have to start my life at zero at 33 years old. I don't even know what will happen with my two kids. I will probably need to leave them to their father since I can't even provide for myself and I will need time to settle for myself independently. 

We are slowly getting back into a red situation  and being hired will be difficult, especially when I am currently alone with the kids. I do need money but I also need advices. I am really disappointed he called it quits last night and leaving me dealing with all this alone. Does someone went through the same thing and giving me some words. It would be highly appreciated, especially on how to tell the kids that everything will be different now.

Thank you to have least read this. I don't expect much honestly. I needed to vent a little while I am slowly saying goodbye to the things I owned around me and will never have again.
