I have this. I'm not really sure about diagnoses etc. But I want to make a point about this:

how would you treat someone who recovered memories of molestation versus someone who knew all along? Would you think of them as having similar or dissimilar experiences?

People with genuine recovered memories also knew all along. Just not consciously. When the memories come back, or you put the pieces together, it can be like suddenly noticing background music is playing (I borrowed this from another poster but can't remember who, sorry). There will probably be signs that your body and your unconscious mind knew. You just didn't consciously think of it.

Anyway, regardless of what you do or don't remember, I would expect a T to treat things exactly the same - to repair the damage and help you heal. It's about what you individually need.
