I totally accept that I'm diabetic, but I don't personally "suffer". I get on with it. If you do feel that diabetes is something you suffer, that's a shame, and I totally respect your right to use the phrase "suffer from diabetes" about YOURSELF. But not about ME. Not all of us suffer. Given the friends I've made from this site and elsewhere, I'd say I've had some really interesting and good things come out of having diabetes, to be honest. But that's just my experience.
So yes, I do find it offensive that someone else is deciding whether I'm to be pitied or not.
And of course there are other serious things to worry about in the world, but actually, when you've had diabetes a while, and when you've had it from childhood or adolescence, that drip-drip-drip of people deciding who you are and whether you 'suffer' or not can really [expletive deleted] your head up. So I'm 100% behind anyone who makes a stand on this. And while you're at it - the DVLA form says the same thing, and that annoys me too...
