Does a feeling of anxiety cover the feeling of satiation? Satiation is a soft signal, so does the feeling of anxiety drown out the signal? We also know there is a cortisol ghrelin link which should drive hunger.
So what is the cause? Could there be a belief that is the cause of anxiety? I was raised with unattainable by me expectations placed on me by my parents. The goal post kept changing, always out of range. This created anxiety, which I took over keeping on myself. Trained in anxiety. Abandon the belief that I should strive for anything, and the anxiety should go away.
