Our Fears Can Change the Reality of the Situation

At times, our worries and anxieties can defeat us. In addition, our worried 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 show. 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.

D.Instead of worrying about something that probably won’t happen, concentrate on whatyou 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.
