So my procedure actually just involved having a needle stuck in it a couple times, which I was not exactly totally on board with but in hindsight I don't regret at all. The folks I was with said they preferred not returning anyone to their homeland who might "go postal" and damage their reputation more or less. I'd gotten hurt, pretty seriously but not quite life-altering, so I think that was part of the calculus for potential PTSD and issues down the road.

Before the aforementioned reason for the trip, I was somewhat prone to panick attacks and generally super anxious. Now, just generally not at all outside of romantic relationships & existential anxiety (which might not be sympathetic nervous system anxiety I guess). I ended up in IT roles where pressure would've killed me, and now it doesn't matter if everything's on fire, I'm kind of disturbingly unnerved as one colleague put it. I'm still glad to be out of those kinds of roles, but that's an example.
