Please you sit alone, take a notebook & write down the reason of your anger. What are the causes of your anger. It may be some thing from the childhood or you may think that you are deprived of some thing. Then I can give you advice. At the moment you just think that good akhlaq is half ISLAM. Anger leads to rage & rage leads to fight. So please when you feel, take a glass of water. If you are standing sit down & read darood sharif.
Inshallah you will over come this habit.
