Since Janshares has already answered your question better than I could, I'm only adding something that I think is related and something that I think you may want to learn a little more about IF it applies to your divorce:
It has now been established that there can be PTSD when people become the targets of what is called "legal abuse". This is essentially abuse directed at someone by the court system/court process in which lies are presented about the person; and the person hasn't had the opportunity to see those lies corrected in court records.
I've been building a site that focuses on this and other divorce-related matters. There's a page on it that has several videos on PTSD from court/divorce proceedings; and clicking on the videos will get you to some links to more information. There's also a section on "verbal/emotional abuse", but what's interesting with that is that verbal/emotional abuse aren't always a matter of just a nasty tone used. Evans points out the kind of things that people say that can have serious effects on their "target". She prefers "target" over "victim" because a lot of people don't like to think of themselves as "victims". Whether it's legal abuse or emotional abuse, quite a job can be done on people who either don't get the right kind of help, don't see something happen that might help them feel as if "reality" has been acknowledged, or else never quite get back to feeling their "full size self inside" and instead continue to remain feeling very small inside.
"Self-actualizing" is believed to be what can only happen once other needs (including emotional) have been met. (If you haven't seen Maslow's Hierarchy of Needs, or seen it recently, look it up. It may give you a starting point to start addressing where/what is is that's stopping you from emotionally getting past things.) (With the legal abuse thing, one example in the videos is a woman (the case isn't a divorce) who continues to suffer the effects twenty years later.
I wasn't going to post a link to my personal writing site because a lot of stuff there (and on the related sites) is nowhere near complete; but if you want, go to my profile, click on the link I'm going to post now, get to my personal writing site, and then there (in the left-hand sidebar) you'll see a link to "Divorce Perspectives".
I'm just wondering if it's something about how the case was handled, or something leading to it, or following it, that's really at the root of things for you.
