I read this both because I have dealt with anxiety and depression, and because I've dealt with loved ones or other people I interact with who are dealing with severe anger issues, anxiety, or depression.
In my opinion, this is a helpful book for dealing with people (either oneself or others) who are experiencing severe anxiety, depression, or anger issues. It goes into why people may have these issues, what goes on for them physically and mentally, and teaches de-escalation strategies- some that one can apply to oneself, and some to use with others. I found all of that information useful. I did not agree with some of the author's personal opinions, but those are not a big part of this book and do not take away from the usefulness of other parts of this book.
I would recommend this book for anyone looking for strategies to deal with their own or others' anger, anxiety, or depression, and to reference sections as needed. This is definitely a book that I will be coming back to parts of.
I read this to not necessarily deal with other people and their issues, but as someone who has trauma-based "explosions" (and not as a self-help book, either...people should really be in therapy for these things). What my therapist/my psychiatrist and I have been working on for years to keep things under control is succinctly described with this book. It's more clinical than I was expecting (re: going into the scientific/psychological reasons for each type of outburst), and having the snippets of case studies helped put all of the science and theoretical into context...there was this one description of a woman exploding about every minor thing due to PTSD...it had me *shook*:
"Hypnosis is nothing more than paying close attention to one thing to keep from paying attention to another. A very common way people with PTSD do this is by getting involved in small irritations.
...Trish knows she's being too crabby, but she can't stop herself. People just don't pay attention to what they're doing. Leaving the lights on costs a fortune, but the kids could care less. They don't pay the bills. And look at the mud on the carpet! She marches the kids down to clean it up. Her husband suggests that she's being a bit overbearing. Trish hits the roof...
Exorbitant bills, mud in the carpet, and tiny slights by loved ones become huge to people with PTSD. If you're fighting, and least you don't have to think."
