Hello lovely people.
I am researching this phobia for the first time. I have actually never thrown up in my life, and because of this I from around age 12-19 I had a severe phobia of vomiting. I am now nearly 21. I have never vomited, but I have done a lot of mental work to make myself okay with it. I have reached an acceptance that my body is smart and will do what is best. If I am ill and I vomit, that is not a scary thing. It would be scary if my body could not protect me. As long as I do not drink too much or eat food that tastes funny, I am taking good care not to be sick. If I wash my hands routinely, and stay away from those who are sick, I will likely be okay, too. Maybe one day I will vomit, and it may be uncomfortable for a few minutes, but I am not allowing those few minutes of discomfort ruin my life. I am not afraid of a little bit of fright or discomfort.
It has been a huge challenge for me to tell myself these things. I knew I was mostly cured from my phobia when my boyfriend had food poisoning last year. He vomited and I went to his apartment to take care of him. I ended up kissing him. This may sound disgusting, but I will so full of love for him, and I realized that he didn't gross me out. The only thing that would have kept me from coming to his aid that day would have been my fear of vomiting. And I am so glad that possibly exposing myself to a sickness did not get in the way of my love for him. I ended up not getting the sickness at all.
My advice to you is that you need to try to let this go. I know it is hard and scary. But this is not something worth ruling your life. It is nothing. Diarrhea, sore throats, depression. These things are all unpleasant. But what is worse? Living each and every day in fear, or once every few years letting your body vomit to heal from a virus or bacteria?
Best to all of you.
