Triggered by an obese man on the bus

I take public transit. I was on my way home. A morbidly obese man got on the bus and sat a couple row ahead of me. THIS POST IS NOT TO SHAME THE MAN. I know being that obese is an eating disorder as well. He started eating takeout food he has and I just.... couldn't take it. Something in me just got triggered. My anorexia shrieked at me to move. I got up and move. All I could think of was the calories he was consuming. In my mind I was screaming at him. This was the first time I was triggered like that. Even from the back of the bus I could still smell the food. It was a very uncomfortable bus ride.

Anyone else triggered by people eating around them?
