Prepare a list of things to do in case of panicked

out calming things that tell you the opposite of your fears.
Then you can repeat these things to yourself when the panic
starts to come.
Prepare a list of things to do in case of panicked
feelings, and it will be ready for you when you need it. Fill it
with lots of soothing messages and ideas of calming things
to do. I find this to be a very helpful tool and am never
without my small notebook that has these positive
affirmations in it.
Panic can be a very scary thing to go through,
especially if you're alone. Preparing for when the panic
comes can really help reduce the panic, and even
sometimes help to prevent it.
Another great tool to combating anxiety and stress is
to use visualization.
CALM YOURSELF WITH
VISUALIZATION
The purpose of visualization is to enable you to quickly
clear mental stress, tension, and anxious thinking. The
visualization can be used when feeling stressed and is
particularly useful when your mind is racing with fearful,
anxious thinking.
This visualization process, when practiced frequently, is
very effective for eliminating deep-seated mental anxieties
or intrusive thoughts. To gain maximum benefit, the
exercise must be carried out for longer then 10 minutes at a
time, as anything shorter will not bring noticeable results.
