I'm glad some of you find it so fucking hilarious! My son has type 1 diabetes. He requires insulin every day or he dies. That stark.
When he was first diagnosed 10yrs ago I was devastated, and terrified that he now had a disease that could kill. However, we learned to live with it and for the most part he lives a normal life. The fear of him dying is still there, it's still a possibility, but I know we are lucky enough to live somewhere with an NHS, and he has access to medical care etc, so I am able to quieten that fearful voice.
Now however, thanks to the fuckwits in the Tory party, a referendum that broke electoral laws, and the most inept govt run by the biggest bunch of clowns ever, there is the extremely likely scenario that we could be facing a shortage of insulin in the UK come April next year.
My son could die. 
Yes, of course the EU will still sell us insulin. That's not the problem. The problem is the fact that a no deal Brexit will result in chaos at the ports. Where the fuck do you think the insulin will be stuck? It only takes a day or two of chaos to fuck up the entire supply line.
It's all very well saying "well stock up then!". We barely get enough to last us every 4 week repeat prescription as it is. There is no leeway to stock up! And I doubt the NHS has either the storage capacity or the finances to stockpile enough to ride this out. So yes, it is entirely possible that we could run out of insulin and what then?
I wish I had confidence in this govt to prepare properly for this, but going by their performance in everything so far, I doubt they could organise the proverbial piss-up in a brewery.
So, pardon me if I worry myself sick over this while some of you find it ever so amusingly entertaining.
