I was thinking more about your question. I wonder if the disassociative disorder is similar to a spectrum of Autism as many of them behave like that. Now I am not saying that you are autistic, could be a possiblity or just a similarity, hmm I wonder.
I think that it is good that you are a psycology student. But I hope that you will not let the self defeating attitudes that can come from PTSD get in your way. Maybe if you make sure to keep a journal with your own history and look at it in a completely objective way. That is what I do, only I don't really have a journal but I do a lot of the why research. I don't blame myself for my past. I really look at it objectively.
I only look for the profiles of the abusers and the whole family dimention and how I reacted and all the different behaviors, especially what was behind it. That is really important, not just the abuse but the why behind it.
That is what PTSD victims don't get sometimes. They just look at the abuse but not the real profile of the abuser. See I did that and it helps alot. Because now I can track my own reactions and address the reasons why I do the things I do today. There is not a blame thing, guilt thing now for me. The only thing that we can really change is how we can see now and concentrate on our own behavior patterns. And when we look back at our own actions and forms of addressing or reacting to the abuse, well we can see the many whys of what we are today and we can work on it.
That is what I meant by keeping in check Sevenmile. You have to make sure that you don't let the PTSD get in the way. You have to make sure your not trying to fit something to blame yourself with or add more scare etc. You have to be very objective and make sure you stay with that by asking questions and not just adding un-needed concern.
I hope that helps, I would like to know what you find out. You got my number so to speak now. My number is easy to remember Open Eyes
