When people have said the words triggered I usually get a bit confused because I have normal reactions of sadness or happiness after a big event but my episodes don't immediately happen afterward. Usually, a build up of stressors eventually causes me to slowly dip into depression and from there I go upward eventually. Maybe that's only because medication helps delay it, not sure on that. I know before medication my emotions were quite wild and it was hard to map them all. That's actually a challenging, much debated issue in the psychological profession from what I've heard.
