Pisces. I totally understand where you are coming from. I got to the point where if I felt full--I felt like I binged/cheated.
You do need to eat more than that though. You seem like you need structure to function correctly with food. I know I did.
I hit a point in my life, I was terrified of food. I couldn't eat and if I did I would throw it up. anorexia/bulemia.
What helped me was studying nutrition. Understanding Basal Metabolic Rate, and Active metabolic Rate. Once I got numbers. I felt I had a guide. And since I understood the physiology of food alot better, I was no longer terrified everything would make me fat. (I had obese family members).

Figure out your BMR and your AMR (active metabolic rate) and then use those as guides to figure out how you can eat healthily and lose weight.
For example my BMR is 2392. That is alot. Explains how I got this heavy. If you drop 1000 cs from that it is 1392. 1000*7 =7000 70000/3500 =2 lbs loss per week. Meaning I will lose 2lbs a week if I drop my caloric intake to 1392.
Trust me, I know it is a struggle to find a happy medium when you are a person who puts 100% into everything you do.
