IMHO, From what I know about counseling, they are only guides really to steer you in the right direction. 99% of the real work is done by those seeing the counselor. They can't do the work for us, just like we can't make an alcoholic stop drinking.
I never did see a counselor after my abusive marriage ended. I did most of the work on my own because I couldn't afford it. I read what I could, researched, and talked to other women who had been abused. I can say with certainty that I am so much better mentally than I was three years ago.
