I'm keeping aware of a couple of anniversaries-- it may not be the sole source of my symptoms, but I think weather changes start to remind me. I think the biggest life-altering trauma was my dad's suicide in my childhood-- it was intense for a month leading up to it, and there was a total shift including everything around me because it affected the whole family, traumatized, no interventions. That date just passed. I know I also lost a significant other a few years back, who had been living with me, and that date comes up early October. So, when the leaves start to change. . . I just keep aware of it. But I also notice years when I was happy to notice "I got through it, no surprise flashbacks connected to it". There's some music that I associate with the last loss-- a few years back that song played, while checking out the fall leaves on a fall drive. But in keeping aware of it, the flashback wasn't so intense, and I recovered a lot better because I was aware of it. Theres a song called "Free Bird" and it was also played at his funeral, and for some reason J.J. Cale (which my roommate likes to play) was also causing me anxiety related to grief, however, I've been learning to de-sensitive to it as well, and I also still can enjoy the music, a bit. . .
I think what happens are that there are some triggers to do with time of year, weather, but when there are more triggers going on, as that happens to happen, it can be hard to map, keep track of.
It doesn't have to be torturous for me either. I can practice mindfulness and enjoy the leaves just as they are, maybe a nod back to the trigger, but allowing myself to stay present and feel safe (although when discussing this, I sense a bit of discomfort. . . it's all survivable though and I know that).
