Fear is the enemy. Fear is what feeds our anxiety and nourishes our sensitive nerves. Stress is normal but if it becomes overwhelming and we feel we've lost control that's the point that we pass into anxiety disorder. Our nervous system becomes hyper sensitive: every small worry and improbable threat becomes magnified many times over.
We imagine we have all kinds of life-threatening illnesses, imagination and Google provide the symptoms, the finest doctors in the land can't change our minds. Or we develop social anxiety or agoraphobia as our mind tries to protect us from imagined threats by making us avoid people and staying home.
It's tiring work fighting anxiety and this can lead to depletion which is to say depression. We have entered a toxic cycle of symptoms and bad thoughts causing fear which floods our nervous system causing more sensitivity which causes more symptoms causing more fear hormones causing more nervous sensitivity and on and on we go.
If only we could stop frightening ourselves half to death every few minutes. Maybe we can: through understanding and reassurance and by simply stop fighting. Fighting causes more strain and tension, things we need less of not more.
UNDERSTAND that if doctors and blood tests and scans say you're physically fine and it's all due to anxiety then they're right. Believe them. If it looks like a duck and it quacks like a duck then it's probably a duck. UNDERSTAND that your nervous system has reached breaking point and become hyper sensitive and this is the true cause of our symptoms and bad feelings.
Be REASSURED that the power of anxiety is limited and it can't kill you or disable you or make you lose your mind.
Be REASSURED that you can recover no matter how long and how deeply you have suffered the moment you stop prolonging your illness by flooding your nerves with fear hormones every 5 minutes. It isn't necessary and it doesn't help.
So work with your doctor, consider medications, try talking cures such as CBT and explore the self-help paths to recovery contained in books and YouTube.
But FACE the fact that it's 'only' anxiety. Stop fighting your anxiety and ACCEPT all the symptoms and bad feelings for the moment. FLOAT through each day feeling that some outside force is propelling you forward. And LET TIME PASS: you spent months and years getting into this state, allow time to recover.
And the greatest of these is ACCEPTANCE (for the time being) because it robs fear of its power.
