Do you have a student overdraft?
While it's commendable that you're helping your family with money, bear in mind that student funding is there to support you, not your family. It's a bit of a worry if you've hit your overdraft limit so early in the academic year.Going forward, you need to sort out a budget for yourself so you don't get into this position again. If you approach your university's hardship fund I'm sure they'll be able to help with that. They might also be able to advise you of where you can point your family for help if they're having financial difficulties. It's not fair on you that you need to struggle with your finances too.
