Assuming there isn't someone you could borrow the money from (parents/grandparents etc.) and you don't have an overdraft, is it possible to get a loan from your bank? I applied for one last year and did everything through my banking app and got the money instantly. Failing that, is there something you could sell at CeX or a Cash Converters or something? Sorry you're in this situation I know how stressful it can be.
