There are things to be very angry about in certain times. It is better to silence yourself and hold back. You may say things in which you wish you never did. We all have. The main thing is taking charge of your own actions and what you say. Ask yourself, Is this worth doing in the long term? Will you have criminal charges because you couldn't control your actions? Your freedom is worth more then to have someone else control you and sometimes they will unknowingly. Work on seeing what is beyond the issue by you seeing a better future with every day making effort to overcome the situations you no longer will deal with. Taking ownership on your actions is key to having a better life instead of regret in which there is nothing you can do to take it back.
