How do i get rid of my fear of vomiting?

See a psychiatrist.: You need to see a psychiatrist to get properly diagnosed since vomitting is merely a symptom of an underlying problem.

Fear of Vomit(ing): Emetophobia refers to intense, irrational fear of vomit/vomiting -including seeing/smelling vomit, seeing/hearing someone else vomit, feeling nauseated, etc. Cognitive-behavioral therapy (cbt) -particularly the behavioral component involving exposure to the fear(s) (usually gradual exposure)- is considered the most effective treatment. A clinical psychologist who specializes in phobias can help.
