Stress, frustration, grief, anger...all of those kinds of things can can cause me to feel like destroying things to get a clean slate and start over or whatever, or even just to try to get someone to notice -- a cry for help -- when all is not well with me. And in my own case, that has in the past occasionally included thoughts of homicide. Taking every thought captive and finding alternate courses of action when the thoughts are destructive is how I deal with that today, and I encourage you to learn to tell Mr. Feelings to just chill for a bit in the back of your bus whenever he tries to get into the driver's seat.
