If you have difficulty with verbally abusive family and you need extra skills, I recommend "the Verbally Abusive Relationship" by Dr Patricia Evans. Recommended to me by a therapist and facilitated me leaving my first husband.

Breaks down verbal abuse strategies so you can spot them, and gives you some tools to combat them and prevent the attacks from landing.

Harder to find is the Gentle Art of Verbal Self Defense By Dr Suzette Elgin (RIP.) she was called Ozarque on LJ and used to share wonderful linguistics essays and essays on eldering. I miss her.
