Food memoir except

In my early years, I was a fan of all sorts of foods. I enjoyed fruits, vegetables, meats, and sweets; I was open to it all. Unfortunately, due to stress from school, bad memories, disagreements, and medical reasons, that habit came to an abrupt end. It began in my early grade school years, with food becoming an enemy of mine almost overnight. Junk food and grease-covered pizza became a regular meal, and my mom worried herself sick, despite the fact that it didn’t seem to have any adverse health problems. I stayed skinny, and energetic as always. Unfortunately, I lost my taste and openness towards food. I became a picky eater almost overnight, a nasty habit that’s I've yet to shake.
