                                         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 your anxious moments. 

     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. 2_____

When unexpectedly having thoughts that make you fearful or anxious, challenge those thoughts by asking

yourself questions that will maintain objectivity and common sense.

     Be smart in how you deal with your fears and anxieties. Do not try to deal with everything all at once.

When facing a current or upcoming task that makes you anxious, break the task into a series of smaller steps.

3_____ 

     Remember that all the worrying in the world will not change anything. Most of what we worry about never

comes true. 4_____ Everything else you can leave in the hands of God.

     It is not easy to deal with all of our 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. 5_____

A. Take it one step at a time and things will work out.

B. When feeling anxious, stop what you are doing and try to do something relaxing.

C. This will give you the confidence to manage your anxiety.

D. Instead of worrying about something that probably won't happen, concentrate on what you are able to do.

E. The next time you feel depressed, review your list and think about the good things that you have in your life.

F. A good way to manage your worry is to challenge your negative thinking with positive statements and

    realistic thinking.

G. Completing these smaller tasks one at a time will make the stress more manageable and increases your 

    chances of success.
