Wow, just lost a huge post! 
Hi Smithfield, briefly, I felt that since you said you had perhaps put your counselor in a surrogate mother role, that you went into 'people please' mode as a reflex of childhood training. It reminded me of codependency. The reflex jumped over your entire brain and thus made the real you invisible.
I find myself in codependency as a helper. But it makes the one being helped invisible because they are then denied to live in their moment. Concepts still a little confusing/complex to my understanding. 
In my reading/searching, I have come across 'distorted thinking' which I find also applies to me (a childhood/EA legacy). So my opinions could be summed up as imho or better as just guessing more accurately.
I also felt agreement with MizzyFizzy's gut feeling about your counselor asking you to "go there" in the first place.
I will post about toxic middle sister later; it is so kind of you to remember.
Hi Oneplusone! I check into Stately Homes intermittantly, but rarely post these days. It is still helpful to me though.
Yes, after 4 years, I feel that I will never heal to the point of as if it never happened. I can only evolve the best I can.
Hi GoingForGoalWeight. Wonderful post, full of feelings=love it. no victims only VICORIOUS 2012...I'm in. 
RaspberryMilkshake-hang in there. Monitor your visit to try to identify the dynamics. If you can't quite put it into words, trust your gut feelings and keep a journal of the circumstances/transactions. We can try to help you identify what's normal (as if we'd know
) and what's not normal (experts lined up!). Enjoy the trip over and the trip back-it may be the best part of the adventure. I have 512 blessed miles between here and mil!
