Working through issues is not the same as the issues themselves and when they happened; it is not a rehash but an entirely new experience. Because we all are unique in the specifics of our life experiences, my experience of abuse and your experience of abuse are different, even though they were both "abuse". T's, over the years of practice, have become very knowledgeable about working with people who have been abused; they haven't seen "your" abuse because they have not seen you, but they have seen abuse like yours and helped that previous person.

It's like we're all trying to cross a canyon on a rope bridge and T is in charge of helping each person with their fear. You may have a fear of heights, I might have a fear the bridge won't hold me. Different fears but still relevant to crossing a canyon on a rope bridge and my degree of fear might be greater/lesser than the previous person who had a fear the bridge wouldn't hold them and/or I may have that fear but never have a bridge break but some poor person T helped before (to get across THIS bridge) might have had a previous bridge break on them! It is always new for T because it is one-on-one and that's always. . . one-on-one, not able to be duplicated (since apparently there's no such word as duplicatable :-)

I think the "more important" question is apples to oranges; which do you want for yourself and/or why can you not have both?
