You posted at almost 20:00 and said you've eaten an omelette, 1 piece of bread and some fruit.
If that's all you've eaten today, no wonder you're hungry!
You can eat much more than that - at leat 3 good meals a day, or 5 smaller ones if it suits you, making sure that you control the amount of carbohydrate you eat. You don't have to go to extremely low carbs, like some of us (me!), but make sure that most of your diet is made up of protein, fat (if you can tolerate it) and 'good' carbs form fresh vegetables and a small amount of fruit.
The diet I follow is somewhere on the Low Carb Diet thread, under 'Viv's Diet'. The example I give is very low carb and quite high in fat - it works out at about 25 grams of carb per day max. My blood lipids are okay on it, and I'm losing weight - but everyone's different. Also my bg readings seem to be almost 'normal', and stable (with metformin).
If you want to eat more carbs, just add them on, using a carb counter book such as the 'Calories, Carbs and Fat Bible' to help you work out what to eat.
Have a look around here at all the threads dealing with diets of various types (not everyone does low carb) and you'll find plenty that you can safely eat. Diabetes may be a life sentence in some ways, - it's certainly a change in lifestyle - but no-one is asking you to starve yourself to death. Just find out as much as you can about it, and work out an eating plan that suits you.
I'm afraid that potatoes, grains, pasta, bread and flour, and other starchy vegetables and sugary fruits are out. But there's an awful lot left - honestly! like fish, meat, steak, eggs, cheese, fresh veg, some fruits - I can go on. You need never be hungry again. And you can still drink alcohol - in carefully controlled moderation.
Promise!
Lots of people on here to help, so just keep asking.

At leat 2 litres of water a day - good for you in any case.
