I have to admit that I mostly avoid them to the extent that I can. Sometimes, of course, they pop up unexpectedly. Then I just have to wait out the impact. Understanding what's happening helps. I know what's going on & what I can expect as a result. I will also admit though that occasionally I even consciously seek out a trigger; because truth be told there is a sense in which I love what they do to me.

In terms of coping mechanisms, the main thing I will sometimes do is to simply hold a picture of the trigger lightly in my mind & "breathe into it", so to speak. I may also touch the area of my chest over my heart lightly with the tips of the fingers of one hand as a sign of acceptance of & affection for the trigger. I then allow the picture to disintegrate, or float away, at whatever speed it is inclined to do so. This is a technique I gleaned from my reading of the writings of the Buddhist nun Ani Pema Chodron.
