F(17 about to be 18) looking for housing aid for F47 mother

Hey everyone, I’ve been scouring the internet for any kind of housing aid and I could really use some help. The situation is: we’re 2800$ behind on our mortgage and if we don’t come up with it by the 27th then we will be foreclosed on. Im beginning to feel like we are out of options. I have two little sisters in elementary school and I don’t want this for them.
