Another worst heart break of my life was when my bf brought his new gf in office

I controlled a lot but couldn't and rushed into the bathroom and cried my heart out, some of my colleagues back bited about me how drama queen I was for crying over such stupid things, my boss called me for some signature and I went, when I went infront of my boss my painful emotions were still fresh so being stupid I even cried infront of my boss, my boss told what happened and rushed me to my house in office car so that I could rest that day, I felt ashamed of being unprofessional but when heart is hurt nothing can calm it in that moment.
