Our brains (all of us) like to simplify the world. Once you accept that the CSA was significant it is easy to blame a lot on it. That may actually be a good thing as then there are less issues you have to concentrate on to fix. If you need to get to an answer of 12 then it doesn't matter if the procedure was 3*4, 6+3+3, or (3+3)*2.

If I can get to a decent level of self worth then it doesn't matter if what was the primary destroyer. (not saying this is a fix for all CSA issues)

Just a thought.
