So I went to my doctor to get anti-depressants and ended up with news that my blood sugar, cholesterol and white blood cell count were all too high. I've seen the diabetic nurse although I haven't an official diagnosis yet. I now have to wait 3 months to do another blood test before that can happen apparently . He did give me a rather scary diet sheet that basically said I could eat very little apart from perhaps the diet sheet itself. Then he gave me another pamphlet that was very contradictory to the diet sheet. I have a couple of friends who have diabetes who have calmed my fears and put me on track. What I'm most grateful for is having a reason for my tiredness, thirst etc. I'm a fan of forums so this place is great for me. I have no idea about measurements or what mine are but I expect I will find out next time I see the doctor, and if I don't I'm sure I will be able to ask the right questions after reading all the posts here.
