Countless thousands have felt exactly as you do. Countless thousands have recovered their quiet mind. And so will you.
Your nervous system is responding perfectly normally to what you are subjecting it to. Anxiety overload. It has put up with so much for so long and now it's complaining.
Fear of fear is behind all anxiety symptoms. It's not what lies outside your front door that frightens you. It's the fear of feeling fear if you go outside. A panic attack is the fear that you are about to feel overwhelming fear.
What's happened is that anxiety overload has caused your nervous system to become over-sensitised and in that state it produces all the symptoms we know only too well.
The symptoms cause fear. The fear causes more nervous sensitisation. Sensitisation causes more symptoms which cause more fear. Which causes more sensitisation. You are caught in a vicious circle that is self perpetuating.
For recovery you have to stop 'battling' and fighting your anxiety symptoms. Fighting causes more stress and tension. Your nervous system needs less. So do the opposite instead.
Rather than fight the panic attacks, the bad feelings, the agoraphobia, the health anxiety, accept them for the time being. Offer no resistance, let them come. Accept them completely for the moment despite how unsettling those symptoms are. They cannot kill you, disable you or make you lose your mind. So why fear them? Frame your mind for Acceptance instead.
Do not seek to avoid the bad feelings, don't try to block them out or lose yourself in distraction. Face them head on and pass through your angst and panic.
When you truly accept then you no longer flood your nerves with fear hormones and gradually your nervous system recovers from the over sensitivity - and the bad feelings cease. But you must let time pass, this is no quick fix.
The Acceptance method for recovery from anxiety and nervous depletion was devised many years ago by Doctor Claire Weekes and set out in her first book 'Hope and help for your nerves' also titled 'Self help for your nerves' (the same book). Her protocols for recovery can be summed up in six words: Face, Accept, Float, Let time pass. Her book is available for a few pounds/bucks new or used on Amazon and Ebay. It offers understanding, reassurance and a road to respite and recovery.
Doctor David Barlow, Emeritus Professor of Psychiatry at Boston University wrote:
"By thinking outside the box the brilliant physician Claire Weekes created a treatment protocol to the unending benefit of tens of millions of patients over the years."
Whatever course of action you take I hope you soon experience respite and eventual recovery from all your symptoms.
