I have an intense fear of anything pertaining to vomiting. I'm afraid of getting a stomach virus and feel the need to wash my hands a lot when I hear people have been sick. I'm also afraid of someone vomiting near me and even hearing someone throw up makes my heart beat rapidly. I also can't stand seeing people vomit in movies or on TV and even hearing stories about it bothers me. This started at age 4 when my sister threw up on me in the car. I just looked down at the vomit and started crying and screaming and I avoided my sister the rest of the day. I also caught the stomach flu as a child and had to go to the hospital for severe dehydration. Is my fear normal or am I a complete psychopath? Is there anything I can do about this?
