The Roman philosopher and statesman Seneca once said, "There are more things to alarm us than to harm us, and we suffer more often in apprehension than reality."
Have you ever worried yourself sick about the possibility of something awful happening? Or one thing happens, and you're absolutely positive it will lead to a second and then a third awful thing. The dominoes are going to fall, and the result will be devastating, you are just certain of it. We all do this from time to time. It means far more suffering than is necessary. "...we suffer more often in apprehension than reality." Yes, it's true. And we're easily alarmed when, in reality, much of what we fear never will harm us or happen to us.
For that reason, it's good to examine your thoughts when such a process begins. As soon as you notice that you're building a strong case for disaster after just one small event, check your thoughts. Ask yourself what you fear most. Then ask what that would mean for your life. Why would it be so terrible? When you answer what it would mean, ask the same questions of that situation. If that thing also happened, what do you fear most as a result? Why would that be so terrible? Keep going with the questions, and you'll get to the real core of your fear. Then you can deal with the reality of your fear rather than possibilities. Try to avoid the "always," "never, and "devastating" words when you think of possibilities. That will do more to alarm you than harm you! It's all in how you view things, and your attitude and language make a difference.
