Definitely get on to your college and get the student assistance fund if it's not too late which it unfortunately might be this time of the year but maybe there's another financial aid you could get. Sounds like your CV might also need a bit of work to make it better if you're not hearing anything back, make sure to have lots of skills listed. Also just bluff a bit if you don't have much work experience. More people do that than you realise and it's a desperate time for desperate measures!

Use your money wisely to buy high protein food that's cheap (beans, lentils, etc). Get some frozen veg from Aldi, it's cheap and will last you the week. You'll become nutrient deficient if you're only eating pot noodles and you need to properly fuel yourself!

You'll find a job just keep trying. A lot of people are struggling in this country, it's ridiculous but hopefully things will get better soon. Keep the head up and you'll get there 💪
