I spoiled everything ! Now I'm convinced that Insulin Resistance is incurable :(

A while ago I discovered that I have IR. I tried everything and kept tweaking my diet and my life style to feel better. I must say that it worked. After many years of struggle, I started having a clear mind and energy. I stopped feeling sluggish after meals, my face cleared up and my anxiety was under control (not 100% healed TBH) until I had to go on a trip for 10 days where I couldn't control what I eat. From a low carb high protein diet, I found myself eating high carb and low or even no protein at all. The last day of that trip, I had an excruciating headache after dinner that I kept getting even after coming back. It took me a few days to get rid off. Now I feel like I spoiled everything. I have acne again, I have insomnia, I'm hungry all the time, tired all the time and on top of anxiety, I'm getting some bouts of depression. My conclusion: IR is incurable. Once we mess up with our healthy habits we should expect a violent reaction from our bodies.
