Unless it's causing a ptsd response, like unwanted flashbacks, dysregulated emotions, or a fight/flight response? I wouldn't call this being "triggered ". Being triggered, in a ptsd sense, is something that's going to cause really devastating amounts of distress.
In that sense? No. I don't trigger myself. I have enough problems witthout compounding things so they're uncontrollable.
But there are definitely times when I get a bit of morbid and unhelpful fascination with things (tv, news articles, etc) that relate to my trauma in some way. And I don't think that's particularly remarkable. My trauma fundamentally changed my life - why wouldn't it interest me?
There are also times when I've engaged with thoughts and memories in unproductive ways. But while that is sometimes 'distressing' and untherapeutic, I think it's still a far (faaaaar) cry off being 'triggered'. There are lots and lots of things in this world that remind me of my trauma. But that doesn't mean they've 'triggered' me. It just means it's a distressing reminder.
I don't think it's even remotely helpful calling everything a "trigger" that a) relates to my trauma somehow and b) is distressing. Sexual assault is a distressing topic. For everyone. That's normal and healthy. I get more distressed perhaps than some when confronted with those topics, particularly if it's unexpected and uncontrollable, because of my personal experience.
But when my ptsd is "triggered"? Completely different scenario plays out. Completely. Different.
