I should probably give a brief rundown of what's been going on with me before I ask my question. In February, I had surgery to remove one ovary, fallopian tube and my appendix. My left ovary had a cyst on it bigger than a football (yes, I'm rather notorious to the doctors over there now). At the 6 week mark, my doctor ran a bunch of tests on me. Yesterday, I found out I have "prediabetes" they did an H1C test on me which came out at a 6.0" and it shouldn't be higher than 5.7. I have an appointment with a dietician on the 5th of April which I am entirely dreading. I feel like everything's just falling apart. It's been issue after issue with me lately and I'm not sure I can do this.
I looked on the ADA website, which personally, didn't help me one bit. There weren't many hard and fast guidelines, just recipes that had a bunch of ingredients that I don't like. I don't like most veggies, so this is going to be impossible. It looks like they're going to put me on a 2000 calorie ADA diet. Googled it didn't find much good info. Part of me wants to say to heck with it and just go on about my business because by the way this sounds, I won't be eating anything. I'm overweight, and now I feel like people are going to look at me and go "oh, of course she has prediabetes, she's FAT". I was pretty much inconsolable over this yesterday. I'm overwhelmed and not sure what to think/do. Most of the stuff I saw listed on the ada website is stuff I already do and apparently that didn't work well.
Sorry if I'm ranting, I just don't know what to think or do at the moment.

The advice you have been given here is very good; all the nutrition labels on foods in the store are based on a 2000 calorie a day plan. Also, that is what your appointment with the dietician is for -- that's her job ... to give you that 2000 calorie diet plan that you can follow for the rest of your life if you want to. 2000 calories allows you quite a bit of food really, esp if you choose wisely ...
