This sounds a lot like my own story. Your last sentence in particular sends chills down my spine, because that was exactly where I was stuck for perhaps 15 years. (I was diagnosed at 14 and CGMs would not be available for more than a decade still.)
Please don't give up! It's absolutely possible to break through this mental block and improve your results and mindset step by step. It is a tough journey, but it can be empowering.
I don't know where you're at now, but for me the change started with honestly tracking my data and looking the truth in the eye. I learnt to review the data regularly and think about my results, and the possible interventions I could do.
