Hi Jen,
I am also newly diagnosed with pre-diabetes and I can 100% understand your condition. I am also menopausal and am on HRT, have blurry vision (although my prescription has changed) and have bad sleep patterns. I did my first day NHS course for reversing this condition and discovered that stress and anxiety, along with less than 7 hours sleep a night can contribute to higher blood sugar levels. Considering I suffer from those in spades, it was a bit of a wake up call. I guess the stresses of life have a far wider effect on our bodies than I previously thought.
I am going to take my own advice and try to learn to relax!!
