I am still trying to figure this out, but I am pretty sure my sister-in-law is a trigger because anytime i have to interact with her, I feel like a small depressive loop begins. Mania, on the other hand, is usually several things that come together like a perfect storm. More daylight, exciting events, high anxiety level.....then boom....mania. At least these are the patterns I think exist. I am trying to track this as a way to prevent future occurances.
