Oh dear, all that work on the brink of being for nothing? Harsh, but you'll get through it - you're tough enough to have made it this far. Your story is so similar that of my adoptive mother, she's a five-foot tough cookie as well (we don't actually get along, but I can at least appreciate certain qualities of hers).
Do you have any friends living nearby? If you do, I'm sure at least one of them would let you crash with them for a bit if you can't stay where you are. Even if you don't have the money, at least you have the skills to start over, if needs be.
Yes, it is harsh. Long term, I am not sure of the outcome. Short term, I am staying on the property, and setting up my own systems of survival. Sometimes, us short gals are the toughest cookies of all.
