Much of the work done in psychotherapy involves increasing awareness of emotions, such as anger, and finding ways to use them constructively. 

Anger can be informative and motivating. For someone who usually feels content, a feeling of anger can inform her that something is not right.  The anger can act as a separating energy, motivating her to separate from what is harmful.

If we ignore our anger, it may become manifested in less conscious ways.  Suppressed anger can become experienced as physical symptoms and/or illness.   The anger may “build up” and become expressed at later times, sometimes explosively or of proportion to the situation at hand.  Without acknowledging our natural emotions as they arise, we may convince ourselves that everything is okay even when it isn’t, and thus be less motivated to make the changes that could actually improve the situation.

If you are chronically angry, have difficulty controlling it, or are otherwise finding it interfering with your overall wellbeing, it would be a good idea to get help.  Exploring how your anger is connected to current and/or past experiences, working to understand and resolve any related underlying tension, and developing skills for coping with the anger when it arises can be extremely beneficial.
