I have something similar. It gets triggered by a certain sound. Right now I'm at war with my so called neighbors. They've been assaulting me with that sound since January 14th (before that they were stamping and pounding on the walls, much scarier than you'd think). I have become very slightly desensitized to the noise, but not completely. So they are still making me react to the noise which makes me hateful and enraged. That's sort of like having Satan in my head, I guess. This trigger thing is the reason I'm disabled, and then the more classic symptoms of schizophrenia. It's hell and I wish to God it were all over. Sorry - I'm in a horrible space right now, thanks to their triggering me constantly.
