User blog comment:DarkShadowThePhantomWolf/AGGH I FIGURED OUT WHY I VOMITED YESTERDAY/@comment-31213163-20180711063821/@comment-32392816-20180711205500

Also, vomiting during an anxiety attack is completely normal. The symptoms I was feeling were lightheadedness, overheating, and nausea.

Being nauseous can easily trick someone's brain into thinking that their body needs to vomit, therefor that is what I did.
