MerylStreep- we have not left yet- and certainly not left with NO Deal ... yet.
We have had stressful weeks as Brexit is already affecting us personally. First the uncertainty of exchange rates- as our only income is in Sterling. But in last couple of weeks- we find that we will be covered by health insurance in Switzerland and UK - but no longer any cover for rest of EU, including France on our doorstep. That means no more going shopping or walking, skiing in nearby France, no more driving to UK, no cover when we go to Italy, etc. We can't get Travel Insurance from UK as we are not residents- can't get cover from here as it doesn't exist (Swiss residents are covered in EU by their health insurance- from which we are exempt). And our Insurer is now refusing to renew our insurance for our UK flat- as they don't want to insure owners living in EU, due to Brexit.
Despite promises by Gove and others- Brits in EU are finding themselves in dire straigths through NO fault of their own, and despite very careful and informed planning. Yes, we do live on tenderhooks at the moment.
