for a long time, i too thought i was the only one who suffered from this debilitating fear. it started when i was a young child and quite frankly - i still struggle with it 40 years later. when i was a child, my mother would scold me for becoming sick - yelled at me about how it ruined "her" night and she had laundry to do (i threw up in bed) and yada yada. she never comforted me - in fact, she used to stand behind me at the toilet and perform the heimlich maneuver so that i would "get it all out" so that she could go back to bed. to this day, a little nausea sends me into full blown panic and many times i have to isolate myself from the world in order to be able to deal with it. i actually leave home or work and take myself somewhere that i know i will be undetected........as in your case - i spent many many many hours obsessing about the "what if's" - it has ruined a good chunk of my life. i wish i had an answer for you (and me) - i am just beginning to make little progress steps. i hope to be able to get this ugliness under control so that i can enjoy life. i pray for all of my fellow emet sufferers as well.
