You wont vomit, and I have bad anxiety too!

For an odd reason it hasn't been acting up for the past three days which is a relief!

Anyhow, it's the pizza and your stomach stretching back out to fit more food since when you starve yourself your ACTUAL stomach will shrink. It will get better with time and wait until that pizza goes threw you, you will feel better.

See us Emetophobes don't understand normal bodily functions. Your stomach is being normal. I promise.
