Help me not be homeless

My family recently experienced some bad car troubles that we had to sink all of our money into fixing, and now rent for this month is past due and our water is in danger of being disconnected if we don't pay on it by the 12th of September. This comes after my mom being let go from her salaried job earlier this summer, in June; we've been trying to play catch-up from the aftermath of that ever since, and it clearly hasn't worked out. I absolutely wouldn't be asking for help like this if it wasn't absolutely necessary to keeping the 3 of us in a home. My mom is a single mom and has fought for us every step of the way, but right now we're all at a loss on what to do. Anything anyone can throw our way is immensely helpful, thank you so much.
