Dropped out of my Masters but already spent some of the student loan what to do?

Hi all,
Can someone please give me advice about my situation.
I applied for the MA course at the uni and I thought I picked the right one for me and declined other offers from other unis (I based my decision on their fees, they were the cheapest). When I applied the uni website stated clearly that we could choose our own optional modules, and they also got other perks (e.g. free foreign language course, nursery on site etc.). However, when I turned up for the induction day it turned out that we couldn't; the tutors already picked what they're going to teach us (I wasn't aware of this before, I even asked the admins team prior to the enrolment and they did say that I can choose my own optional modules). Needless to say how upset, frustrated and disappointed I was, I then decided to withdraw and they finished the withdrawal process within a day! Now, after reading and doing some research on the Internet I know that I need to return my loan money back to SLC but the problem is I've already spent some of the money to buy books for the course, fixing my old laptop, buying new study gear (notebooks& other stationery) and in the past 3-4 weeks I've been to the uni to do their language course which obviously money spent there as well. I'm now spent about one thousand pound of the three thousand ish loan, am utterly devastated as I don't how to find a grand to put back to the Student loan to pay back to them, I don't know what to do. Any advice will be greatly appreciated.
Thank you.

I already have student finance from my undergraduate degree, I pay a percentage off this every month, so will they not just add this to my total student finance money

You'll need to work out how much you can afford to pay back each month, and then make a repayment plan with student finance. As long as you're paying back as much as you can afford they'll be fine with it - even if it's only £5 per month. But once you've made the repayment plan, you need to stick to it and make the agreed repayments, unless your circumstances change and you tell them of this.

So you'll need to get a job or claim JSA or something to have some form of income.
Then you need to write down your outgoings/expenses. Start with the important ones - rent, council tax, food etc. Remember to include anything like a mobile phone contract where you're tied into a set payment.
Use these figures to work out how much you can afford to pay student finance each week/month and phone them and tell them.
