I find the act of eating rather gross and will only eat for sustenance, not pleasure. I just don't like eating. I don't think I'm overweight, and no traumatic event with food. Do I have a disorder?

Gross is a meaning, we build many meanings for different reasons. Great to hear that you don't have overweight, also, as an ecological check up: a nutrition expert could assess your weight and health, sometimes I wish I could see the state of my internal organs so that I can effectively adjust my diet. Meanings, flavors and the size window of the palace of sensations... The tongue and taste buds could provide enigmatic answers. Eating better to live with a higher quality of life the next month or in ten years is something special. Our body works differently at each stage of life, today's nutrients will serve the body in twenty years ... May the Joy, Balance and Wisdom continue in your breathing :)
