Our Fears Can Change the Reality of the Situation

At times, our worries and anxieties can defeat us. In addition, our worries can change our understanding of what is reality and what is not. Here is a brief list of techniques that you can use to help gain a better viewpoint on things during the anxious moments.

__小题1:__ A person should take a deep breath and try to find something to do for a few minutes to get their mind off the problem. A person could get some fresh air, listen to some music, or do an activity that will give them a fresh perspective on things.

Remember that our fearful thoughts are made to seem worse and can make the problem worse. __小题2:___When unexpectedly having thoughts that make you fearful or anxious, challenge these thoughts by asking yourself positive questions that will maintain objectivity and common sense.

It is not easy to deal with all the fears and worries. When your fears and anxieties have the best of you, try to calm down and then get the facts of the situation. The key is to take it slow. All you can do is do your best each day, hope for the best, and when something does happen, take it easy.__ 小题5:___
