Jobs for students. What am I doing wrong???

I am over here studying as a student and I literally cannot find a job. I have applied for countless jobs online all with zero word back. I tried going into places and asking and everyone of them said to check online. It’s gotten to the point where I can’t afford food or do washing in my accommodation. And I have only went out once since I’ve been in here in September so I’m spending my money wisely it’s just that I have ran out of my saving. I had to pay my family back with my student loan and my next instalment isn’t going to be enough to pay for the rent and I’m shitting myself to the point where I have to miss classes and fly home as I have a job back there. Therefore I’m basically paying for nothing but I’m terrified of debt. I don’t see what’s wrong with my CV and I do have other qualifications other than just GCSE I have all the way up to a level 5. And at that I’m only applying for simple jobs in the first place.

I’m sorry this is a bit of a rant but I literally have no idea what to do.
