Well, we've been together for just over two years now, and it seems as though we are going through a little rough patch. Things were fine for so long, just the occasional tiff, but now that's becoming a bit too regular. I'm trying my best. I keep feeding you insulin and you keep saying it's not enough! Then when I try extra hard you turn round and leave me shaking and tearful. That's no way to treat one of your closest friends. Perhaps we need counselling?
