Nothing ever 'sorts itself out'. This is a challenging time for the UK. It is for many nations, with another recession looming, populism growing in politics, and a nut-job in the White House. But there is absolutely nothing but war that is scarier than Brexit is for us right now, with our own nut-job (Bojo), likely to end up in 10 Downing Street, as our PM.
But lookie here... the fortunes of the United Kingdom have risen and fallen for hundreds or years, like they do in most countries. Greed and a refusal by government to address our many problems will mean that, for now, and who knows for how long, we will be a country in decline.
But, unless you have political aspirations, or a large fortune to lose, there is no point in worrying yourself about it. What will be, will be. You alone can't change the course of events.
