I just don’t think that this drama on tv is anything like my experience, possibly because my experience is happening to me and it’s not entertaining.
Often I feel like shit watching so many tv shows, i have multiple traumas as well and its surprising what will trigger you even if its not obvious. While my traumas aren't usual subjects for "ptsd themed" episodes, I went through a period of not watching tv at all because I felt like most tv shows's protagonists are written to be selfish and narcissistic toxic people, and I was disgusted by these characters being loved and celebrated by those around me who weren't making the same connections. I hated that toxic behavior was being normalized and even laughed at. (think about homer simpson and his relationships with his family and neighbors, he's an inconsiderate asshole to everyone and his children would have had major psychological trauma as they aged due to his actions. and yet he is an extremely beloved character and millions of people laugh over the absurdity. but for people who grew up with parents who actually acted like homer the jokes don't quite land.) I found shaun the sheep to be a pretty decent binge watch during this period.
The show that made me the most angry was Greys Anatomy, pretty much everybody on that show had PTSD, but the only person who they made an effort towards writing accurately and explored the chronic issues with was the ex military character. more of that "2 miracle therapy sessions" then heading back to being a world-class surgeon, it was complete bullshit. However... one of the more recent seasons gave me hope, they had actually put in actual research and effort towards a story line about a character who escaped an abusive marriage. As it turns out the writer of those episodes has a chronic disability herself, and put the effort in. Granted the arc had an annoyingly happy resolution, just like so many other shows before it. I stumbled on this article last year, and it had an interesting argument that I think could be applied to portrayal of trauma in tv.
My Disability Story Isn’t For Your Catharsis (disclaimer: I neither agree nor disagree with the article, but it was definitely food for thought about the target audience for trauma stories)
I myself wouldn't use the term "popular" to describe PTSD, although I don't think its necessarily bad. Take this example: in 1960 the prevalence of people on the autistic spectrum was estimated 2 or 4 affected per 10,000 children, the cdc in america now puts estimates at 1 per 59 children. So how do we partially explain the rise over the last 50 years? (yes there are many unknown factors as well) One thing that has directly contributed to the rate rise is the definitions and diagnosing of children showing signs of being on the autistic spectrum. PTSD rates are probably following suit as the way we define and diagnose the disorder evolve. PTSD and related conditions are more commonly being treated, leading to better prevalence data, which in turn brings it into societies eye.
Mental health issues including PTSD are still a pretty unknown concept to the general population, and there is a lot of ignorance going around, its hard to elicit meaningful empathy for those living with conditions when you yourself have not experienced them or have not been educated about them. I can say one thing on the side of the popularizing of it in media, it raises awareness to the public. While its early days yet, and its apparently most easily explained to people through stories about soldiers coming back from a war, I have hope that shows will evolve to explore the lesser known causes and intricacies.
