What is the efficacious way to calm urself down?

I think you are stressed. Being impatient is being stressed. You know when im being impatient,and when it is easy for my blood to boil, i luck myself at my room, and i shout for a sec. Just to release the tension. Even at office, i will go to Ladies Room and shout there, it might sound weird, but its my own way of releasing the stress. Sometimes, i listen to good music, and sing with it.

well... hmp... i get irritated sometimes but im just so lucky that people arround me are very unerstanding on my mood swings... But... i have someone that makes me calmn everytime im in a bad mood or mad of something... and its my boss(my boyfriend)... i think on your case.. you should always think before you react... if you get mad and had said something bad... stop for awhile and think about what you have done or said... then say sorry to the person you hurt and explain your side.. that's the first step to control your temper. its not easy but after a few days or weeks trying.. youll find your self giving time to think before you react.
