I think I have that too, but more of a fear of dying or some terrible trauma happening. All that started after I had severe anxiety attacks. I am constantly afraid that I will have a heart attack in the car. It that is what you are saying.
I am working on that though. I force myself to confront the fear and don't let it control my day to day life.
I know that doesnt' have to do with anything related to the question, but I can't think of anything that inhibits me.
