While I highly recommend Rose Rosetree's book, Become The Most Important Person in the Room, which teaches the empath how to function healthfully, I need to talk about style.
If you are the kind of person who likes to be poked in the ribs by your teacher until you crack a smile, and who likes clown noses on your newscasters, then you will love this book. However, if you are from the "just the facts, ma'am" camp, well, consider this a lesson in tolerance. I personally found the style a little off-putting at first, but since the content is so useful, I learned to overlook it.
If you are an empath struggling with picking up other people's stuff, do yourself a favor and order this book. But in terms of the style, consider yourself forewarned.
