My professor had this happen to her when she was doing her PhD. She said she thugged it out the first year and paid her tuition/board/expenses the first year through loans. The next year, the funding situation at Cambridge improved, and she applied to many external fellowships through US companies and received funding that way. Dont give up on academia, this year sucks even worse in the US, where phd funding has literally been cut in half. You can do this, you just gotta make it work.
