EMETOPHOBIA

Emetophobia:   Emetophobia is a condition where an individual fears vomiting or others vomiting.  If you have emetophobia, you may fear vomiting alone or in public equally. You may frequently experience feeling sick but you are probably no more at risk of being sick than most people. Vomiting is associated with an overwhelming fear and panic. Some people fear losing control, becoming very ill or that others find you repulsive.

As a result you try too hard to avoid a wide range of situations and activities that you believe might increase of risk vomiting.
