Hello dear, The description provided by you here of low mood and depression, bouts/fits of anger-aggression, impulsivity, feelings of emotional detachment, irritability, mood swings/instability, and negative thoughts all point towards depressive episode. However from your account I think a detailed assessment including personality, and socio-enviornmental factors is required. Also a psychological intervention of psychotherapy can help you get the desired results. Hence please discuss with your psychiatrist these options including addition of psychotherapy to your treatment regimen. Hope this helps you. Best wishes for your health and future.
