I Was Hungry, Yet Had To Get Somewhere So I

I was hungry, yet had to get somewhere so I waited to eat. I was feeling anxious because of the hunger yet soon it went away. Then about 30 minutes later I bought some green juice and had a little. Soon my stomach started to hurt. I was maybe 2 hours later that I finally ate some tuna and salad. At that point my stomach was tight feeling and hurt. Is it because I waited so long to eat ?
