Hi everybody,
This board is my newest aid in my "first aid kit". But bibliotherapy has always been my first course of action. The ones already posted are great. Here are a couple more:
Controlling People: Patricia EvansThis has a great "teddy bear" analogy. That is, many Ns see other humans as their teddy bears to play with them as they direct...
Too Nice for Your Own Good: Duke RobinsonGreat for an approval junkie like me.
Stop Walking on Eggshells by Paul Mason and Randi KrugerThis is really about BPD, but N coexists with this disorder quite a bit. Biggest eye-opener I read. Lots of survival tips in here, esp if you are dealing with a rage-aholic.
Difficult Conversations by Douglas Stone, Bruce Patton, and Sheila HeenThis is a great book for anybody, esp. voiceless people who need voice! This book helped me prepare for a confrontation with other family members re the problem N in our lives. My comments didn't change anybody else's behavior, but I felt heard and empowered, which lowered my frustration level quite a bit. Besides, the only behavior we can change is our own!

Basic message: say what you need to say in the least harmful and effective way. (and you do need to say it).
OK, last suggestion:
Writing as a Way of Healing by Louise DeSalvoOK, now that some have figured out what's going on, now what do we do? Writing down what happened and
how we felt about it (linking events and feelings) will help us heal! And it's kind of garbage: we gotta take it out, or it piles up. And we all have garbage.
Uh oh, I can see my summaries are getting longer...better sign off now. Good luck everyone! cheers, S.
