This sounds abit like, me, i am 38 year old, I haven't been sick since I was 4, and I actually threw up for the first time on Friday, in 34 years, Like you I didn't panick, it wasn't a great feeling, and once you done it, you do feel better, I agree, my emetophobia isn't cured, but i got better understanding in what it feels like to throw up, so i think, it very small steps, but on my way to getting better
