journaling helps (for me, at least) in identifying your triggers. i write every day, good or bad and keep a very, very close eye on my moods and mood shifts & also document it when i SI. eventually you start to see the connections. at least then you can see the warning signs when you're about to get triggered. not that it makes the urge go away.....but the more self-aware you are, the better. get to know yourself, your moods, your actions and how it's all connected the best you can.
