I've been encouraged to think a bit about triggers lately, and the highest manias I have had started with this kind of thinking. Sudden clarity of thought involving some kind of mission. They start innocuously enough, but they're hooks that catch at my brain. Next time, I'm going to try not taking the bait, if I can.
I'm not saying this is happening to you, but it's my experience. So... take care. I'm really glad you are feeling better, though.
