Until you've lived in another country you won't appreciate what you have in the UK. So go! You'll soon come back with your tail between your legs.
Wish it was as easy as that. I currently live and work in Norway. I love Scotland, where I grew up. I love the people and the friendliness.
But I wouldn't move back. We have a great work/life balance. We get time off work if family members are sick or need help. We've lost loads of weight. We can get doctors' appointments, MRI scans and operations without huge waiting lists.
The schooling is awful though. Wouldn't recommend it to the OP. Though the International Schools are good (and teach in English).
I read the British papers and am horrified. I visit my family and see homeless drug addicts everywhere. For the first time last year, after the Brexit vote, I felt ashamed to be British.
I still want to return to the UK, but it's hard to justify when I currently live in a country where there is much greater equality. We pay a lot of tax and I am happy to do so as it means nobody has to live on the streets.
Britain used to be more like Norway. It's been moving right for the last thirty seven years. It's not an improvement.
