YES, TR, the struggle is real!!
Parts of us that experienced abuse absolutely know they were abused. Parts of us that didn't absolutely know they were never abused. That is a part of how dissociation protects. We exposed our system to our new therapist earlier this week, and then went into denial again. The ones in us that step forward with denial absolutely deny that we have DID or that any abuse occurred.
Because - for them - it didn't.
We have struggled with denial of various intensity for many, many years. (Even though some of our abusers have admitted abusing us, those parts of us still think we are making it up!
Dissociation is just that good.

I am going to let the same question stand, so someone else can answer it from their own perspective.
