Take a deep breath and relax. Go for a jog or fast walk and get some endorphins flowing. Get a massage or a long soak in the bathtub with some candles. Time to refocus on things that matter.
Life is too short. Keep your head above the water and avoid escalating negativity by communicating with these people. Ignore them. You can interact with only a limited amount of people in your life, choose positively, choose wisely.
Breaks are for losers. Get back to work.
