I need help with £100

I don’t really use Reddit often but today I really need someone’s help. I’m a student at university who’s going through mental and financial problems, the money I receive each term is never enough to cover my rent, groceries and other bills that need to be paid. My mother also struggles financially but always always always pulls through for me even at her lowest, because she wants to see me leave with a degree and she has faith that her little girl will succeed in the future and will never have to go through financial issues ever again. This money wouldn’t be to pay any debts or bills, but to take my mother out for a nice meal out in central London so she can have a day where she doesn’t have to worry about paying for anything for once and she can relax and take a day off just like she deserves.
£100 is the limit but to be honest anything really helps as long as I get to give my mum the day out that she truly deserves, she is such a hard worker and I’d love to show my appreciation x
