Hi Jannu123,
Do you live close to uni? Is commuting from home a possibility for the first year?
If not get in touch with the student services department at NTU as they most likely have some form of income assessed bursary or hardship fund that you can apply for. Considering your parent's circumstance you should be getting the maximum amount of student finance which is nearly 8k. I remember going to an open day at Nottingham Trent a few years ago and it was so expensive!!
The main thing you need to do is budget. Write down all your major outgoings and how much you need each month as then you can see what your short of. Tbh the max amount of student finance should really cover you. If it doesn't start looking in other places, can you get your phone bill be cheaper? do you have stuff you could sell on ebay before you go? Even though you might not be able to find a job atm, retail will start advertising for xmas temps soon that could boost you by about £1000 over November & December which will be a big help. Check on NTU's student union website for jobs too, the uni i'm at have student staff behind the bar, library and tuck shop.
I think everyone at some point has struggled with money at university but unfortunately that's just the way it is sometimes. If you can't afford to go out with friends then don't. Budget your food and take a packed lunch in everyday to save money. If you put yourself out there and ask people for help you'll get it.
Good luck to you, have a great time at uni!
