How would exposure therapy for someone like me work? Pictures and movies of vomit do not make me anxious. The only things that do are hearing that someone I was near might be sick and I only feel slight anxiety from that. It doesn't last for long and I don't dwell on it. What does make me very anxious is someone coughing, and it has to be a nasty cough for me to be scared, and being near someone I know is vomiting or about to.
