You cope with it by doing nothing. That's right, nothing. You accept it for the time being. You agree to co-exist with it for the moment. You engage in 'masterly inactivity' to use the words of the woman who cracked the anxiety code and cured tens of millions of people of their anxiety disorder.
And most important of all: you must stop fighting these feelings when they come. Do the exact opposite of what instinct tells you and you will recover.
If you continue to fight the feelings you generate more tension and stress: more of the fear hormones such as cortisol and adrenaline. More fear hormones are the last thing your over-sensitised nervous system needs right now.
So Accept your symptoms for the moment, unpleasant though they are. But it must be true 100% acceptance, not just "putting up with".
Don't let first fear be followed by a flash of second fear. Eventually your nerves lose their over-sensitivity, of course: you're no longer swamping them with fear hormones.
The power of anxiety is limited. It will not kill you, disable you or make you lose your mind. All it can do is subject you to bad feelings and troublesome thoughts. Anxiety is a toothless tiger. Its only power is to imitate organic illness and make every minor worry and concern in your life become exaggerated ten fold.
You are a rock on the shore. The ocean sends mighty waves to crash around and over you. Then the sea draws back. Great is the fury of the sea but the rock endures. You are that rock.
To recover you need understanding, an end to bewilderment and a road plan for recovery/desensitisation of your nervous system.
You have two choices. Continue to frighten youself to death every five minutes or Acceptance. Choose Acceptance. Choose the quiet mind that follows. Choose having your life back.
Of course you can do it, you are among the bravest people on Earth: people with anxiety disorder are the most courageous folk of all. Everybody knows that.
