It's double hard for me as I also have borderline traits to and triggers from that as well. I can usually tell the borderline triggers. My bipolar moods seem to come and go as they please. If I am in a manic period I'm sure I have more triggers too! My biggest trigger seems to be any disruption to my normal routine. Now that could just be my personality. I really have no idea how to tell the difference from a mood trigger and personality trigger
