I've never encountered such a book as tells about emotions directly except this one.
Sometimes I've been overwhelmed by sudden emotions mainly triggered by rejection. Even in the case that rejection seemed to be no big deal, I was hurt anyway and had trouble shaking it off. What's more, I've suffered from bad headache without causes for decades.
I've tried to recognize what's wrong with me through books and lectures for a long time. Now I think I get to notice what's going on inside me. Nevertheless, I still struggle to deal with some kind of emotions; Against my will,I just can't help but feel!
I hope learning emotion oriented practice of this book can be real help for me.
