The level of general ignorance about psychology is daunting, so I will explain further.
Everybody experiences anger. Some people find legitimate ways of releasing it. Others, however, were socialized from early childhood into believing that anger is not something they should ever allow themselves to experience. So they repress and often erect their incapacity to become angry into some kind of a moral badge of honor. In reality, however, all they do is drive themselves into a variety of severe health issues.
How do you recognize a person who represses anger? They nag, criticize, and are very controlling about small things. They are bothered by insignificant details of the actions, speech, clothes, manners, etc. of others. When something bad happens, they keep their emotions under control and act heroically. They repeat the phrase, “I never feel angry” often. When you meet a person like that, you need to know that this is a future stroke patient right there.
If you recognize yourself in this description, I recommend that you try to remember how your family members reacted to your anger when you were a small child. What did they say to you? Were you allowed to experience all of your emotions freely whenever and wherever they came to you? I promise that you will find your answer in those early childhood memories.
