Hello two years ago I had severe panic attacks and anxiety. A german book of guy called "Klaus Bernhardt"
helped me to get rid of this condition. Before I did 6 years of psychotherapie and it does not helped me a lot.
But this book gave after 6 weeks of application such a big relief! I really recommend this book. It is pubslihed in englisch.
I do not get paid for this! I recommend this, because I applied it myself and it changed my life radically.
