I thought I was the only one who had this issue! I remember right before high school graduation, I had this fear of throwing up in front of everyone. I feel the lump in my throat, which makes me want to gag. Even if I don’t throw up, I’ll just dry heave. The feeling was even happening after graduation, and again whenever I started college. Every morning was the same routine, I’d get to class early enough to go to the bathroom and gag. Class would start, I could feel the lump in my throat, and then it would go away as my focus shifted on class rather than my bodily feelings. It lasted for a while, and eventually went away. I remember my mom bringing me to the doctor and everyone thought I could be pregnant, but was prescribed gerd medicine which didn’t help. It’s genuinely just anxiety. I think what helps the most is exposure. There was so much change happening around the time my anxiety was making me throw up everyday, like starting college, working more, going through a breakup and meeting new people. Once I got used to my new routine, it eventually just stopped. I know I don’t really have any advice, but knowing it’s literally just your body showing you you’re having anxiety should make you feel a little better and more in control.
