As someone who suffers from BPD and many other chronic illnesses, this book was very helpful in understanding myself, how to get better, and even gave advice on SET communication. Which me and my significant other can practice in crisis situations. I highly recommend this book to anyone suffering from this illness, or anyone else just trying to understand it themselves. This book was recommended to me by a friend who also suffers from BPD, and has recently passed on due to suicide from this illness. I am grateful to have known him, and thankful he left behind this book of advice. RIP Jake.
