Are you still using hypodermic syringes for your injections?
I only ask, as, being diabetic for 19 years with thousands (if not tens of thousands) of injections, I have injected myself twice using that medieval for of injections and that was my first and second injections. Every other injection I have had until two and bit years ago was through my injector pen(s) and then, two and a bit years ago, I was put on an infusion pump, a rather expensive (give or take $5000) piece of tech which has enabled me to get a far better grip on my control and not spending a single penny on the device, nor all the gubbings that come with it all because of the brilliance of the NHS - Admittedly, there was a waiting list (of six months or so) and I had to have gone on a DAFNE course, but that, to me is only fair.
I also have, in those two and bit years used two GGMS Monitors the (admittedly self-funding) Libre Freestyle (which is now available on the NHS) which I used to monitor my glucose levels and then, over the summer, the HSE allowed me to be prescribed a Dexicom 5 CGMS (which connects directly to my infusion pump) to better allow me to attain better control and because my Hypo awareness (my only real side effect) was next to nothing.
So in nearly two-decades, living in two countries that have similar health care systems, tens of thousands of pounds worth of medical needs (two types of insulin cartridges, needles, pens, testers, test strips, the pump, insulin vials, insertion kits, reservoirs, the Dexicom 5 battery and sensors plus all the out patient appointments and two stays in hospital) I have never ever worried about my medical needs or if I can afford anything and at no point have I had medical insurance. (it's adviced we have it here)
Or, when my step-dad and dad both died of Cancer (bowl and a rare form of genital Cancer respectively) neither of them died knowing that they would owe hundreds of thousands of pounds in medical bills.
