@mike Ah, the age old question. I tend to see myself as a diabetic because it isn’t an optional extra, it’s an integral part of me (and maybe because I don’t remember ever being anything but diabetic). But if talking to medics I tend to say I have diabetes – they have a nasty habit of seeing all diabetics as being the same, therefore I like to make the point that I’m a person with diabetes rather than just a walking disease.
I mused on this eons ago here – http://www.shootuporputup.co.uk/2009/08/what-am-i/
