Low carb diets do increase long term risk of diabetes, so when you followed it a few years ago, it might have contributed to the situation you find yourself in right now.
Since you now have DT2, you must control your carb intake, you no longer have other options.
What do you eat? You say you eat healthy, but have diabetes, cholesterol and excess weight, so something doesn't add up. You need the help of a dietician. I know there is a waiting list, but get on it. In the meantimes, start doing something. In your situation a plant dominant diet might be your best option. Avoid saturated fats for the cholesterol and this includes red meats and processes meats even turkey bacon, and also coconut in any form or shape. And of course, your username, the cheese.
Opt for fish instead of meat, quinoa instead of grains with maybe some rolled oats occasionally, a lot of vegetables but no potatoes, some legumes, soya for cholesterol, and move. Have vegetables at every meal including breakfast. When you will have lost weight, you can reintroduce, flour, rice, potatoes, but if you go on a strict plan, limiting them now will make things easier, because high blood glucose is now an issue you need to control. It can have severe consequences.
You will be eating carbs, but complex ones, such as legumes, vegetables, some fruits (not bananas, not grapes at first).
Your case is made more complicated by the cholesterol, but you can manage both by lowering your weight. Don't aggravate your cholesterol by following the typical MN low carb diet made of meat, more meat and even more meat. Cholesterol is as important as your blood sugar, not matter what online influencer say or sell.
