Banks are acting like utter c***s right now. I wouldn't get too stressed about anything regarding them. If they have defaulted you so what? It buggers off your credit rating in no time anyway. As for bankruptcy, my mate did that a few years ago when he split with his wife. It took him a couple of years before he could borrow money again, but he has a mortgage now and all the rest of it.
Its a game, play it.
