You're only young once. I actually think in a different way to most on this thread. There's always time to go back to the matrix and do the degree, but arguably the peak of your life is between the age of 18 and 27. That's the time you want to spend partying in other countries and living out of a suitcase. There is always time to go back to the UK and enrol in a degree course, who knows, you may never want to rejoin the rat race. I have a degree, but I really hope I never have to use it as I know I will hate the job it 'entitles' me to. It is a back-up, but it's a back-up that is so undesirable I'd consider benefits before it.
I'm 22, but at the end of the year I'm 23. Sounds pessimistic but the late twenties are creeping up. I wish I came out here when I was 18, even more time here at my peak. I had fun at uni, but after freshers year you've seen it all to be honest.
I do strongly suggest you have some 'buffer' money though just in case, a couple of grand to fund the job search and potentially get you a plane home. Or you could just wait until the next student loan payment and take the flight out.
