Aww John, no need to apologise for asking things in here, thats what this forum is here for, anything you want to know just ask, usually someone has the right answer for you.
I would advise that you start testing so that you know whats going on, it is so important that you learn more about the relationship between food and blood glucose, most meters come with a few testing strips, so get yourself a meter and call the surgery insisting that you do need a script for strips.
Have a look around the low carb forum for ideas on recipes and what other people tend to eat, do not worry its not as complicated as it sounds, although its is very normal to feel confused in the beginning; also dont be too scared of low carb, when I say low carb you might not even have to go very low carb, maybe you can do medium carb instead, you see this is where the testing comes in, if a food gives you high blood glucose readings then its obvious that you either need to reduce the amount of that particular food or cut it out altogether. Dont be scared of playing around with all the foods, its quite interesting to learn about the connection between food and bg, and its empowering too, to a large extent it is you that can control your diabetes.
Re the books that you have been reading, I suspect that they give out the old fashioned advice of eating carbs with every meal? This is totally outdated information and actually very dangerous, you have very high blood glucose and its important that you reduce your blood glucose levels to single figures.
Tell why did you not enjoy the meal your wife cooked for you tonight? What foods dont you/do you enjoy? Give us a list maybe then we can advise you.
I seriously suggest you get hold of a meter and get strips prescribed asap, then try the low carb way, just for 2 or 3 days only, you can manage that cant you? I bet you will see your bg drop quickly.
If you still feel that this is not for you, then look up low GI diets instead, google this and you will find loads of info there and if this doesnt appeal either maybe you need to go on taking more and more medication to help you reduce those high bg levels. Bear in mind that too many carbs are not good for anyone, whether they are diabetic or not, so your wife can join you in there too and it can become team work to devise a healthier eating plan for both of you? Some people, esp overweight ones, like I used to be, find that after initially going very low carb they can steadily increase their carb intake as they lose more weight and still keepo their bg levels to that of a non-diabetic.
Re comfort eating, I used to do that too, and of course when you have all those things wrong with you it seems that food is the only pleasure you have left, try and find other things that you can reward yourself with, anything instead of food, also please do consider asking your GP to refer you to a physiotherapist so that you can start to exercise a little bit and all these things will give you confidence as your bg improves and you will lose weight and become fitter.
You need to be patient of course, and do things slowly, but you will get there eventually, you will see, so dont despair
So post a list of the foods you enjoy or dont enjoy, and also write down the meals that you used to eat.
