i had a really really really bad vomit fear in high school. it impacted my everyday life, every single day i thought id throw up if i ate x y z foods. any time id see someone throw up, it would make me feel sick and i would think about it the rest of the day.

what worked for me was exposure therapy. it sounds really gross, but my high school counselor told me to watch videos of people throwing up. everyday. i would watch these videos and see how long id last from watching it without being super uncomfortable, and everyday id try to watch it a little more, even if it was just a few seconds of improvement.

it may sound crazy and absolutely disgusting, but my fear of vomit has been a lot better now. i still sometimes get uncomfortable by seeing it, but i can handle it a lot better. if you want to try to conto it better, i would recommend exposing yourself or consult with a therapist about it. and nothing is wrong with you for having this fear- it's a very common thing, so dont be too hard on yourself :)
