When I'm really angry, just a workout won't do the trick. I have to work out to the point of sheer exhaustion to release all that negative energy.

Having an enjoyable commute helps me a lot. A long walk or pleasant bus ride (with optional music) is time to process emotions and to create a mental break between work and home.

Meditation can also help -- not as a solution at the moment when you're angry, but as a habit that can improve your mindfulness and ability to deal with your own emotions.

My last resort is distraction - reading a book or watching a movie or TV show I know will be engrossing. An hour or two later, the frustration has usually dissipated.

That said, if you're experiencing rage that you can't control, or are on the edge of "snapping" - whether into rage or depression or whatever - I agree with the previous poster who suggested you seek mental health services.

A good therapist can help you come up with better outlets and coping mechanisms, or help you identify what in your life you need to change to avoid circumstances that trigger such frustration. It may take a few tries to find someone who works well with you, so don't get discouraged if the first person you try isn't a good fit.
