Think about yourself in combination with others; you cannot know or stop someone else texting/e-mailing someone and that hasn't caused a car accident that you personally know of, has it?

Either we have to believe we have special powers so that our actions are stronger than other people's (and then you have to think about how many action combinations there are and how you get down to ridiculous beliefs like: if you put your left sock on before your right sock, X will happen; multiply the minute number of combinations possible by a zillion) or you have to realize that, because other people do these things we're afraid of and nothing bad happens, it's not likely to happen around us, either.

Keep focused on the "facts" rather than the feelings for a bit. If you realize that feelings can't predict, then they become less bothersome. Your thinking is only influencing your feelings, not anything or anyone outside of you. Acknowledge that your thinking and feelings are related and are both yours (not some one's/thing's outside of you that can control the future which we can't know), and they lose some of their power to hold your attention and worry you.
