I have an extremely bad temper. Any advice for me to control my anger?

Practise walking or looking away first before reacting. Calm yourself first. Don't say anything yet. You wouldn't want to say anything or do anything you'll regret out of anger. Here's an article on anger management from Mayo Clinic. I hope it helps. http://www.mayoclinic.org/healthy-lifestyle/adult-health/in-depth/anger-management/art-20045434
