Hi. Let me start off saying that anger is a necessary and useful reaction when directed appropriately in a controlled manner. It all boils down to how frequent those episodes are and how you express anger.
Next Steps
A few things which help are a brisk walk when you feel out of control. Calming yourself by deep breathing is quite effective. But once anger subsides analyse what made you angry in the first place. And think of alternate ways to react or avoid similar situations.
