This is a book by Dr.Gabor Mate who is a speaker and well known author about many topics including stress, trauma, ADHD and substance use disorders. The book is When the Body Says No: The Cost of Hidden Stress. I see this issue with some people who in particular have problems with anxiety. They tend to have problems saying no and overcommit themselves and put themselves last. Then their body tends to react to that stress and they begin to have health problems from burn out or simply carrying stress around for too long. This book really highlights how dangerous it really is to your health to do that.
