You have essentially two ways of dealing with unpleasant interactions with others at work. You can "respond", or you can "react". Learn the difference between the two and you'll experience few conflicts while having more control over everyday communication. You'll be happier and feel less exhausted when you go home. If you're a "reactor", it will take practice to make the shift to being a cool responder. Your goal is to remain in control of what you say so that your communication goals are met. With a reactive style of communication, you lose this control and risk becoming a victim of your own emotions.
