Try provident loans, but only if you’re really struggling. I hate the thought of payday loans. As for food, could you use a food bank or lend a small amount of money from family?
Do you mind me asking where in the UK you are? If you’re anywhere near me, I may be able to take you to/from work if I’m not busy working or if it clashes with daughters nursery times.
Theres also a credit union, not sure what you have to do to lend though.
Best of luck 🙂
