I am also open to other work though, I started out in disability care so there is a few options.
So you bought a house even though you have no concrete or viable plan to support yourself, and essentially nothing to offer on the Polish job market, especially in Kielce? With three kids and a wife to support, as well? Whatever were you thinking?
You should have nailed down a steady, reliable and adequate source of income before deciding to move to Poland and buying a house there. It might be impossible now, if it ever was possible.
Sorry, but going from what you have written, I don't see much hope. Perhaps there's something you haven't written that might convince me that this is more than an utterly harebrained scheme that doomed to fail?
