Is it true in your case that the things you most feared, expected the worst for or were terrified over, never actually happened or occured less dramatically than you thought they would turn out?

Have you spend days or even years worrying yourself sick about something or being obsessed over it, only to find that finally you had blown it out of proportion? Even worse, is there anyone out there who may have spent most of his life worrying about something which still hasn’t happened? What effect did it have on your mental and physical health?
