Thought to share this with you all as I've bought this book and it really helps and explain you lots of things about anxiety and how to tackle it, it work for many people and I've just started read this book 2 weeks ago and feel slightly better also waiting to see a CBT counselling in January. The book is called at last a life by Paul David.
Here is the link to buy the book! Highly remmonded and take my advice is drink chamomile (tea (Waitrose is the best) while reading this before you go to bed
And if you want more detail about this man called Paul David (at last a life) and he got a anxiety problem for years but now is anxiety free!
Buy his book, read, listen and take his advices!
