It's really a pitty with that whole Brexit Dilemma. I personally think that it won't be the end of the world but it might cause a painful Decade for UK. Hell a load of corporations are already contemplating on leaving: JPMorgan, Ford, Airbus, Nissan to name a few. Most of them are in the UK as it is a very Corporation friendly Place and has access to the huge EU-Market. This really was not a smart move. I am a bit unsure what to think about Scotland and Ireland. I mean most Scots who voted remain in 2014 did so to stay in the EU, so if they have a Referendum I am pretty sure they will be out, It's questionable though if they will have to go through the normal chanels for a new joining Nation to stay in EU, or if they can just stay in as they have been in until now. 
What I really am afraid of personally is that this will trigger a new round of conflict in Northern Ireland, half of its Counties voted Bremain half Brexit, and if I am not mistaken the line is mainly between Protestants and Catholics once more, I really hope this will not turn out like the 90s again, I still remember very much the Bombings and stuff, that was all when I was starting Highschool and we did a lot about that in politics and english class. Also, once more it's the young folks who have to suffer under this decission. 
If you'd ask me we should be past this national state nonsence, should all be Europeans instead of Englishmen, Spaniards or Germans. I mean we can all keep our cultural heritages and all that stuff without having a national government, EU would work so much better as a Proper federation and not made up of todays national states, (as these are to different in size), but of the next lower level, like have the Bretagne and wales and Northrhinewestphalia be members of that EU. Have a proper 2 chamber Parliament and stuff, this will aparently never happen but one can dream. Anyways political mode off >_< just wanted to give my two cents.
