Then you're worrying unnecessarily. You could choose to worry about all manner of things including insulin dependency right now. What if, what if, what if etc? Equally I could about my needs, my families needs etc. There's no point however, we all have to trust every single day that things will get done, happen as we expect for just about everything, major and minor. It's just too easy to throw the baby out with the bathwater re: Brexit and say everything's going to go wrong/ it's all TM's fault. It won't and it isn't.
So, basically let’s all bury our heads in the sand, and trust the politicians to come up with a solution to the ridiculous mess, cos that has worked so well, so far.
I don’t blame May for this bunch of bollox, I blame you and your ilk who voted for a referendum choice, that had no end game,and you had absolutely no idea of the insurmountable and unsolvable problems that you have inflicted on the 45ish million who didn’t vote for this insanity.
