I remember being afraid of food when I was first diagnosed. It is common and you will get over it as you understand your D more.
MyFitnessPal is a great app for watching your macros. The starred database entries are entered by users and are not always complete and accurate. Unstarred they got from some official info and is accurate. For best results, get a food scale and measuring tools. Weigh and measure everything until you get to the point you can be pretty accurate without doing so. You can also track your exercise. Logging is good because you can also match it with your BG to see what affected you. I know a lot of people who set up a custom item in their database and use it to track BG so they have all their info in one place. You can print it out to take to your CDE too.
Visit bloodsugar101.com. Lots of good info and an explanation of how to test and eat to your meter. All of us are different and so we each need our own diet.
Coffee really doesn't contain carbs if you drink it black. With fake sugar and heavy cream you won't have a lot of carbs either.
I treat myself with very dark chocolate. The 86% that I have now says 30 carbs for the whole bar which is just over 3 oz. I usually only eat one square at a time so about 4 carbs.
I call juice liquid sugar and never drink regular juice. Once in a while I'll have some sugar free cranberry since it is about the only juice that doesn't have much carbs.
I don't use diabetic cookbooks because they are very high in carbs. When I'm not being a slacker I generally eat little starchy stuff. If I'm working out I need more carbs. Most days I have a slice of toast with cheese because I seem to need a dose of carbs in the morning. I usually have a piece of fruit mid morning, melon or berries seem to be a little lower in carbs, bananas higher. I find I need a banana if I do heavy lifting. Lunch is usually lots of non-starchy veggies with lots of protein. Snack is often almonds. Dinner is another pile of non-starchy veggies and protein. Bedtime snack is popcorn and cheese or crackers and cheese. I seem to need a little carbs before bed or I'm really high in the morning. Last night I had some strawberries and did good with those too.
