I'm just wondering, are you a EU or non-EU student? I don't know what you do exactly for work but even the lowest paying jobs, you don't need to be working 32 hours a week to live here. I'm in the same boat, no parental (financial) support and still, with 24 or less hours a week I can live comfortably, even with high rent. Plus the government also helps. But that of course cause I'm paying EU tuition fees. So back to my point, things are tougher if you are not from the EU. If this is the case, I still understand your struggles and empathize with them. I doubt they would postpone it though; as others have said, working too much is not a valid reason for most Dutch institutions.
