Your problem is not that you can't stick to anything. Your problem is believing that there are two phases. A diet one (impossible it seems for you to follow) , and an eating properly later. You chaotically mix and match diet bits from here and there. Yes, fasting can be a tool, but you are misusing it. Do a proper 16:8 every single day. Ultra low calories 600-800 diet can be a tool, because the reason you can't control your sugar is pancreatic fat. Slim the pancreas on an ultra low diet,. sugar is fixed. However you need to follow it for days in a row, not alternating it with whatever and everything.
And you eat wrong. Go back to your posts, and look at the diary you report, how can you even think you will lose weight by eating peanut butter, mayo, honey, pork crunch, chorizo, aioli, cheese, crispy onions .... start by removing these. ,
You were 182lbs when you started this diet in July, you are - unsurprisingly - 189 today. Isn't that enough to ditch this program of high protein and low carb? I know you probably believe your own excuses, injured, tired, stressed, husband, weekend, .....whatever, but at the end of the day, what makes the difference is what you put in your mouth and how many calories you eat.
You have given the low carb craze a go. Didn't work. Accept it is not what works for you , and opt for a healthier way of eating that includes lentils, chickpeas, some fruit, a few tablespoons of whole grains, some seeds such as flaxseeds given your hormonal issues and a great variety of vegetables.
Think polyphenols instead macros. Your gut microbiome is probably working against you. Include six servings of fermented food a day with a lot of fibre and you might be surprised. Give it a go.
