Hi
@Christinepat and welcome from another type 2. It is very overwhelming at first, and the best way I coped with it in the early days was to take each day at a time, and not think about the mammoth task of reducing my blood sugar and losing the 4 stone I needed to. In fact I still haven't lost all the weight, but it is coming off slowly and surely and I'm now into my last stone 7 months later. I think that if I'd thought about the whole 4 stones I'd have just given up as it was too much to take in.
Your IBS will no doubt complicate matters, and I'm afraid I have no experience of this. Most of us T2s cut out, or radically reduce, the amount of carbs we eat. That's bread, spuds, pasta and rice as well as nice stuff like cake! Bizarrely, I found by not eating those things, I stopped feeling hungry all the time.
My single best purchase this year was my BG monitoring kit. By checking my blood glucose before a meal and two hours after, and keeping a food diary, I know what suits me. There is no real one-size-fits-all with diabetes, you have to learn what your body can tolerate.
Finally, it's early days yet and you may fall off the wagon occasionally. If so, don't panic! Dust yourself down and just climb right back up there. A couple of people have told me on this forum that with diabetes each day is a new day, which is heartening.
Best wishes
