Hello dear the irritation and anger could be due to some stressor which is bothering you and making you feel so. This is affecting your relationship with other as well your health. Try discussing about the issues with someone close to take their support and help to solve the issues and stress. Try meditation and deep breathing to calm your mind and involve yourself in your hobbies. Spend time with family and friends to uplift your mood. If required mental health professional help try consulting a psychologist.

The anger or irritability could be due to multiple reasons. Are you having any other symptoms like sleep disturbance/appetite issues. Are you have trouble with concentration/interest levels or motivation. Do you often feel that you have mood swings. Is this anger/irritability worse in the premenstrual period ? When you are angry/frustrated do you do anything to hurt yourself ? If the anger is interfering with your personal/professional life it would make sense to get it evaluated by a psychiatrist who can then suggest next steps.
