Criminology is fascinating, too! :D I think any time we see people act in ways different from the norm, we find ourselves asking - why? What were they thinking? How did they justify this behavior? What combination of biology, environmental factors, circumstances, and choice led to this outcome? etc.
The more we study, the more we learn, and the more we unlock the secrets of our own minds. We (human beings) are one of the most complex and fascinating creatures in the world. I could read and study night and day, my whole life and never learn enough. I, personally, have always been a book-person, and when a subject captures my interest, I dig into every book I can find. I did the same with my PTSD-
Since I'd left an abusive relationship, I dug up books on domestic violence, abusive behavior, the cycle of abuse, anger management, etc. I also started digging into books on schizophrenia (suspected diagnosis of my ex). I've been doing a lot more broad reading lately- interested in addictions, anxiety disorders, depression, OCD, narcissism, sensory processing disorder, etc and any possible connections between all these different things.
Because I am a book-person, I find that the more I throw myself into studies like this, turning my interest and my own personal experiences into an academic pursuit meant to satisfy my curiosity, the easier it is for me to understand and cope with my own issues. Finding people to discuss these topics with is also a help in getting my thoughts and ideas gathered and voiced so they can be analyzed and formed into something coherent.
Unfortunately, this strong focus also makes it a bit difficult for me to handle and process the emotional end of things. Despite my academic understanding of my difficulty and my ability to identify where I'm struggling and where I need more work, I'm simply slow in emotional development. I am an extremely logic-brained person and have always been a bit emotionally disconnected. The intensity of the emotions associated with PTSD were a major shock to deal with and even now a bit difficult to process.
