I believe you are asking what you can do to control your anger?
Start with meditation. Do at least ten minutes every morning and every evening. This will to help you remain calm and able to handle your emotions better.
Remember, your emotions are unconscious responses that are programmed into your subconscious that activate when certain stimuli occur. They are a habit. So, you have to break the habit. If you are constantly in a cycle of negativity and anger, you need to break that. Start to focus on different things. As soon as you realize you are angry change your focus to something that you like and enjoy. Instead of being a victim to your anger, train yourself that it doesn't control you.
You will never get rid of anger. What you have to do is learn that it doesn't control you.
