Bad Day

I have a bad day today, throat not getting better but getting worst. And again, i have scolded those vendors on the phone like they are e most stupid people in the earth! I feel real bad at the end of e day, guilty...I feel i am an evil person and i think everyone in the office is having the same thought. Sighhhhh......i just cannot figure out why i become from bad to worst in scolding people on the phone, or even face to face sometimes, at work. My temper really going haywire these days. Is it the way an old hag behave? Oh my, i know i am going to be an old spinster, but just let me have a relax life k...or least dun make me an evil please~
