It occurred to me that getting “triggered” is always simultaneously a chance to let go. But you have to embrace and accept that energy, and it feels like indigestion for a time.
If you picture a crossbow, the existing tension is a bolt ready to be fired. Getting triggered is releasing it. The “trigger” is pulled. A situation pops up, and a trigger is pulled in you, releasing what was latent. What most people then do is hold onto the bolt and keep it from going anywhere. The energy in the system stays exactly the same, but in the most unpleasant way possible.
You can’t make it go away instantly, but building the habit over time of taking the time to live with it, even for a moment, will eventually weaken the impulse to the point where you forget that that thing ever made you that upset.
