Digger1, I agree with your take on this 100%. It is not avoidance in this case; it is re-framing and working within a tolerable window. With trauma work, it's vital to go at a reasonable pace. As long as you are not avoiding talking, thinking, and feeling, then it is not avoidance.
I think those words may not be the issue so much as in the context in which they are spoken, there is a sense of doom.
For me, it's not the words but Fear--knowing that my defense mechanisms are likely to fail--if I dissociate or have a panic attack. My T. has just informed me that when we go into a memory, if we dissociated at the time, then when we dissociate in recalling the memory, it's just part of the memory itself. Other times, it is a new dissociative reaction to the memory. She wants to keep the processing in a window of tolerance. She also wants to remedy dissociation with the application of Positive Resources.
Positive Resources are tools to stop dissociating and stay present when you catch yourself starting to dissociate, like cold, aroma, holding a rock, a beanie bag or "baby," drinking something hot or cold, movement, and throwing a pillow and catching it.
Any time in therapy when I think the therapist starts to creep near the "stuff I try not to think about," I can dissociate due to my fears of not being prepared for what may come up. There is an internal tension: on one hand, I want to talk about how I feel about the trauma (as you describe it as what bothers me.) But on the other hand, I don't want to risk re-experiencing. That's where I have to speak up if I start dissociating and keep my therapist on the same page. This is very hard for me to do in a new relationship. I am going to have to get used to it with HER.
From my experience, people seldom notice if I dissociate unless an expected response is not given so I guess we have to speak up. And this also leads to doing something about it and taking control.
