Can't get back in control..

Oh dear, Sjm, I'm sorry to hear you cycle didn't achieve the outcome you had no doubt dearly hoped for. I can see how that would be a real body blow and how things could know on from there.

Are you still taking your insulin and so on? Has your eating slipped a bit or are your hormones really getting into the mix of all this?

Of course, I'm not T1 and nor do I use insulin, but it seems reasonable to expect your blood meter records a decent history of your bloods (500 readings or the like?) In that case you have some history at least that you could present if necessary. If your meter has a downloading capacity, perhaps you could download the history to keep, again, just in case you should ever need it.

Other than that, maybe just choose one thing at a time to draw back into line (wherever you have drawn that lie for yourself), then add to it a you feel able.

Look after yourself. High numbers can be a vicious physical and emotional circle. Don't be a stranger.
