Doesn’t have to. You have CritA in spades. ANYTHING can trigger pre-existing PTSD to go symptomatic. Any new trauma, stressor, stress, or loss of a coping mechanism. Your partner’s death triggered yours. It doesn’t matter how they died. The same way that if you quit smoking and it triggered yours it wouldn’t matter that it’s doing something healthy... it’s still a loss of a coping mechanism. - You have the trauma history that makes PTSD possible. - You have the constellation of symptoms that means it’s PTSD instead of something else. *** Overdoses are rarely characterized as suicides, here in the states. For a few reasons. The biggest of which being that it’s impossible to get into someone’s head and know if they were trying to kill themselves, or just looking for a moment of peace / to get high, so investigators look at the situation. Without a suicide note or clear indication of intent to die (like downing a whole bottle of pills) they’re generally ruled as accidental deaths. The second of which is that most insurance & pensions have suicide clauses. Meaning that they don’t pay out if you killed yourself. Your family gets nothing. I’m sure the airline tried to have the death ruled a suicide, so they wouldn’t be liable for any lawsuits from the family. (You can’t be held responsible for someone’s death if they tried to die). I’m sure that coming from Cuba their next suspicion was drug muling... which, in the states, also negates most insurance claims and lawsuits (dying whilst in the commission of a crime), and am equally certain that the airline dumped tons of money into trying to ascertain -or imply- that. Here in the US that type of exclusionary investigation takes at least 2 years, and a good team of lawyers can make it drag on for years and years... preventing the family from receiving any kind of settlement. Every year they keep the manner of death in legal limbo is interest they’re collecting on the millions in the bank, and if they can get the family to drop it, those millions as well. ^^^ This entire section below the asterisks? Is just politics of money and death in the USA. NONE of it affects your diagnosis. Its just the games that multinational corporations (airlines, insurance companies) play to avoid losing money. *** Add in that we’re (American Citizens) still not allowed to travel to/from Cuba??? It’s highly illegal... Giant huge police problem having a whole aircraft FROM Cuba land here. Which means that it’s not a “simple” death being investigated by local police (and insurance and airlines) but also would have roped in the FAA/ DEA/ CIA / FBI / Homeland. Each dealing with their own individual parts & investigations & conflicts... in conjunction with CSIS & related sister agencies in Canada. To be completely honest, I’d be surprised if your friend’s case is completely closed... and not still “part of an ongoing investigation” in at least 2 countries. Possibly more, depending on the nationality of the other passengers, and any kind of cargo in the belly of the plane. These types of things, even when completely innocent, are legal nightmares. ^^^ This entire section below the asterisks? Pure International Law & Politics...Again, has ZERO effect on your diagnosis. Your friend died. The stress of that kicked you into being symptomatic. It didn’t cause your PTSD. It kickstarted it. All the rest is just politics. f*ck that noise. It doesn’t matter. You matter. Your friend matters. Politics? Doesn’t.
