Intermittent fasting for insulin resistance?

So i don’t know if anyone can help me but I’m trying to reverse insulin resistance with a healthy diet and lifestyle and I’ve read online that fasting can be good for blood sugar but then I also read that fasting puts your body under stress and raises cortisol. I have elevated cortisol levels because I’m under a lot of stress and I’m trying my best to lower stress but it’s hard. Also I’m loosing weight right now. I’ve lost like 50 lbs so far. I’m not gonna lie, the diet is the hardest part. I feel like everything I eat is just making the insulin resistance worse so I tend to just not eat which I know is horrible and that probably elevated my cortisol even more. It’s so hard. It’s like a vicious cycle.

Does anyone have any tips for me? Maybe you’ve been through something similar?
