Seriously, I will not empathise with you if knowing full well that the UK economy is down the gurgler you move there anyway then get a crap job for a while. When people prefer to hire their own and not you, an Anglo-Saxon non-British Antipodean. When it’s hard to make friends in a new place and you find the culture different.
Harsh I know but welcome to the immigrant experience. Except you’re not driving a taxi despite having a PhD or running out of money and struggling to eat or having racist shit yelled at you down the street. You have a choice to go back to a place with a fantastic economy where the people are exactly the same as you.
