Anxious eating?

This is been happening for a week and a bit now... basically I'll just be enjoying a meal or a snack and all of a sudden I'll feel really anxious. The first time it Happened I thought it was just butterflies from finally talking to the guy I liked but then if carried on every single time I ate...

I generally just push through but that can make me feel sick.

I don't know what's wrong with me, I'm starting to get scared to eat food now
