Hi LM. Sorry to hear about this. Try not to see what happened in that Chiropractor's office as a "setback" though. I certainly don't see it that way. It was a triggering event and something that you dealt with and now sound like you're moving past. It was what it was and it happens. You're ok now. You didn't fail at anything or do anything wrong so, to me, that means it wasn't a "setback", just an unfortunate incident. You're ok man.
For myself, I've always had a lot of anxiety being handled by a chiropractor the few times I've been. I don't guess the ways I'm being touched in those sessions necessarily relate to the way in which I was touched in my childhood but I always freak out a little when someone's fucking around with my body and/or touching me in what feels like intimate ways. Also, I've had more then one person massage me, (never professionally), and tell me that I was the most tense person they've ever put their hands on. Not that I really even found those massages triggering per say, but all that tension they were feeling comes from somewhere and I know that's all about CSA related issues. Peace,
