Don't really know what to do anymore

Hiya,
I'm a 20 year old female architecture student living in London.

My parents have recently disowned me (they're incredibly strict)
And although I have always supported myself, they did occasionally help with rent and just general money for food.
I barely have money to feed myself most days, and so I'm finding it hard to even focus on my work.

I do have a part time job but I've been very tight on time recently due to uni and haven't been able to work as much as I want to.
I'm incredibly stressed and the lack of money I have is really starting to get to me.
I have 3 months of rent that I need to pay (£2360) and I've run out of personal possessions to sell. I've sold so many precious items like gold and even my MacBook (I have to use an old laptop with a broken screen now)

Anyway, thank you to anyone that has read this far.
I would really appreciate anything, instead of me begging for money I'm asking you to think of this as an investment in a fellow human being.
Thank you
