A someone with Asperger's Syndrome, I have been plagued by anxiety and depression for much of my adult life. I read another book that recommended Mindfulness as a means of dealing with the dreaded 'black dog' and I am so glad that I followed this tip up.
I've now read several books on the subject, but this one is, in my opinion, by far the best. The writing style is very easy to read (unlike some other titles that get bogged down with endless quotes), the instructions are simple and clear to follow and, after following the eight-week programme more or less to the letter, I have found that there have been definite changes in my life. I no longer dwell on the past, I spend more time watching Nature around me and I feel more generally content in myself. The changes feel quite subtle - I do not feel like a completely different person, for example - but, crucially, I have not had an episode of depression since reading this book and my meditation practice has become as much a part of my everyday life as brushing my teeth - it is not a chore, it is something that I look forward to.
If you are going to give Mindfulness a try - and what have you got to lose? - I really recommend this book and CD as your first port of call. It's amazing - I wish I had found it years ago.
