how can i stop getting angry so quickly with people

i have always been very sensitive, the touchy type..i tend to take things personally...like if someone uses a word i don't like or keeps using a word over and over again, it can leave me feeling very angry....i was on the phone earlier and the woman kept using the word 'already'...and i tried to keep patient, but her using that word really wound me up and in the end, i came off feeling uptight with her on the phone...i put the phone down to stop myself from being threatening.


how can i learn to relax and not take what people do so seriously? i think half the time it's because i don't know how to take people.
