There has been some discussion before on this board about whether what happened with your brother was CSA or not. I am not going to be debating that, but I believe that most modern perspectives on csa as well as trauma would consider what happened as abusive. Also, there is rsesearch suggesting that premature babies suffer trauma in the ICU, and this might have particularly been true 60 years ago when you were born. But there can only be c-ptsd if there is trauma.

I could see you as having symptoms potentially in all six areas of the disorder. I am not, however, trained in DSM diagnosis. I have worked with traumatized people for all of my professional career and read scads of professional reports that offered this diagnosis, and I believe the diagnostic criteria are really quite nuanced, much more so than what is written as the major symptoms.

I really agree with Asia, though, in terms of the importance of the disorder or diagnosis. I think that you may make more progress working on changing the behaviors that you have already identified and otherwise working on improving your life than you would in responding to a diagnosis.

And, in general, having a more or less rough childhood doesn't necessarily explain why some develop disorders and some don't. Your past is only one piece of your mental health or your psychological disturbance or your general well-being. Just like some people can total their cars or wrap them around trees and walk away with a bruise or two while others are killed, psychological outcomes are not always predictable by childhood experience.
