When I have severe anxiety from an upcoming event I will get bad stomach pain and vomit so it could be you really are stressed about getting married I use peppermint candy or tea to ease my stomach pain and listen to music to calm down

Social anxiety?

Hi, I can relate to this. I have nervousness from time to time that makes me so anxious that I feel like I either have to use the restroom or throw-up. Tools I use to keep my self lowered instead of heightened is using the 54321 method, if that doesn’t work I used the finger tracing method or if I need something quick I keep salt packets and Altoids in my car and on me. The instant shock of something really salty, minty or sweet helps me redirect my focus. I hope this helped!
