It sounds like you are doing a great job with her! The thing about emetophobia is that most, if not all of us very RARELY become ill. It IS ironic but true. We spend our whole lives freaking out about something that in some cases NEVER happens to us! It is totally irrational, and I am sure she is very aware of that in her logical mind. I certainly always have been, and I first developed it when I was 6. Don't let her feel shame because of it, though.
