You need help with more than eating habits dear. You REALLY need to take care of yourself. Make yourself a first priority today and every day. Low carb doesn't work for everyone, but what I will say is it works for many if not most. Make small changes. Also please eat heart healthy. I'm barely 40 and just had a massive heart attack a month ago..
Ok make small changes. Eat more fruit and veggies, but fruit with MODERATION because fruit does have a natural sugar in them that will raise your sugars.. but it's a better form of sugar than say processed foods or sweets. I take it you have no insurance or you could talk to a nutritionist and find this all out. Do web searches for diabetic meal plans and food information. Also do a search on foods that are bad for folks with kidney damage. I may be mistaken but I believe bananas are something you shouldn't eat a lot of.
Eat more salad with low fat, low carb dressing. Change any bread, rice or pasta to whole grain or wheat. Don't drink any soda. No sweet tea. No fruit juices unless you really read the label. MOST fruit juices are stacked full of added sugar so you think you'[re making a good choice, but in reality you're not. Also if you eat out go online and check the nutritional value of the menu before going. That way you are armed with good options before you walk in. Just know McDonald's has really ZERO good options even the ones we think would be good. and they are not alone in that fact. Several fast food places have ZERO acceptable options. Even subway... I don't know what Jared did or ate before subway, but most of it is high in sodium.. Who knows we may find he has heart issues before too long.
Anyway.. You really need to seek out some support in your area.. See if there are any free diabetes support groups or classes that might be low cost. You will learn so much there. Get online and read read read. I was diagnosed about 20 years ago. I printed out over 1000 sheets of paper on diabetes (I wasn't on insulin back then) and read each and every one of them. I learned so much. When I got put on insulin the only thing I needed to learn was what new foods I needed to tweak to fit into my insulin allowances. Now that I'm a recent heart patient I'm again on the learning curve.
We have to take care of ourselves, you are already seeing the affects of not doing it. Diabetes affects us all different. I know diabetics that have taken worse care than I have and they have no complications while I've had many many many.
Good luck and god bless and keep asking questions here, to your doctor and anyone else that might be able to help
