The answer to your problems lies in the title of this book itself - and some might say an obvious solution to one's fears, and simply put forward, and in some cases, this really does work!
There are so many books out there on this kind of subject, but as many of them; deal only with pretty 'common' scenarios. I suspect the authors of such books would simply say; 'but the same approach applies to all things'. However; on that I would not believe it to be strictly true; I can think of dozens of situations that people may find themselves in that simply cannot be compared with that of say, losing your job; worrying about public speaking, or how will you pay the next bill. Many people have very personal problems/issues which do not fall into any particular category but their own, and so whilst this book does have (though pretty obvious) a great approach, do not think that this will deal in any real detail with perhaps 'your' personal problem.
It is true to say that dealing with any frightening situation is made even more frightening by 'thinking' about it which can often result in our 'running away', and the concept or belief that says that the more frightening things we confront, the less frightening they become - or perhaps to use another term; the less frightening they 'feel', is not always the case. Some people never get used to doing those things we all dislike, and we all react differently, and so it's good to bear this in mind when purchasing this book, and that it is really just another 'analysis' from yet 'another' person, and in the end, it will be 'you' who in fact deals with it.
The author has a way of convincing you to believe that this is the way - and perhaps the only way of beating your fears - and it is one of the better books I have read on the subject, but as all books of its kind, tends to 'generalise' a little too much in some important areas.
