Need assistance for PhD tuition fees

Having started PhD studies at a University, moved to a new apartment with my girl, working for tuition and living costs, everything went fine.

Now, there have been changes at my girl's working place, resulting in less money that she earns. Not the costs for rent, food and so on are still enough, but paying the tuition fees now is a real challange, although I also work besides studying to be able to pay rent and fees. I hope to collect some money here for being able to better come around with my tuition fees and our living costs, as I'm in a quite successfull way to obtaining my PhD and quiting would not be an option, also because so much money has already be spent.
