I can suggest you for meditation. You will understand the various state of mind, also be able to find out the way to be calm and leave your rage or anxiety. My advice is to find out the cause and result of your rage, is it relevant to get that much of mental irritation? And what will be the effect of that. Will it brings a positive result to you?
