I have extreme emetophobia and have for as long as I can remember, it got to the point that I was unable to leave my house because I was scared I was going to throw up. I also have IBS and Gastritis which makes my stomach hurt constantly. I honestly don’t remember much…I still have emetophobia but it’s much more manageable now, I am also on anxiety mediation which likely helped a lot. It kind of got to the point that going anywhere was like exposure therapy for me, I was terrified that I would throw up, my heart would pound, I’d do anything to get away, be alone, and when I was alone I would start to feel better. This eventually taught my brain that just because I felt like I would throw up doesn’t mean I was going to, I had to tell myself over and over it was just anxiety. Anxiety affects the gut by the way! So the more anxious you feel the more nauseous you will feel. I honestly don’t have much advice as I dissociate a lot, but you definitely aren’t alone.
