Anger is a natural response to a threat. However, it becomes a crisis when the individual has a problem controlling his anger. The latter is not a disorder in itself, rather a symptom of other inward mental issues. Anger can be caused by family issues, stress, depression, alcohol abuse, and other related problems. These issues often lead to irritability, feelings of hopelessness and despair, restlessness, and can cause self-destructing thoughts. Anger manifests itself differently within each individual. It can be outward; where aggression is shown in the obvious ways of shouting, cursing, being verbally or physically abusive, etc. It can also be inward; a situation where anger is directed towards oneself. The person thinks low and negatively of himself deny himself things that make him happy and can cause self-harm. A third category is passive; being sarcastic, not talking to people, etc. If you believe you feel angry on most days, and that it is harming your relationships and daily routines, it is best to seek help. There are some tests that your doctor may recommend to diagnose any anger issues. Anger can induce a lot of stress and can harm physical health as well and catching the issue at the right time can help you improve your life. The test may require your blood or urine sample and the test reports will be available within a day.
