Regarding your second post: I wonder if your intense fear of vomiting has to do  with you having been forced fed as a baby- maybe your mother forced food into your mouth and you gagged, feeling like vomiting. I don’t know if you have or can possibly get this kind of information.

I have wondered about this myself. I only know of one traumatic incident with vomiting when I was a baby and that was when I was strapped into a car seat on my first plane ride and I threw up all over myself and the car seat and was stuck in for the whole plane ride. It fits into my fear a little bit because my fear of vomit is proximity-based. I will only feel a little startled if someone throws up outside passing them by on the sidewalk or something. If I am in the same house or room with someone throwing up is when it is the worst I have experienced. My absolute worst fear is being trapped in an enclosed space with vomit.
