Do u have any problems with your workmates at your working place before?

i just had one just now. it all started since yesterday. i argued with Subject A over a small matter and i was angry and told this matter to Subject B about my argument with Subject A. i was just wanted someone to listen my problem. after that, i never believed that Subject B told Subject A that i saying something bad behind her then both of them just argued with me, a big one! now i am not angry of Subject A about always argued with me but i am angry of Subject B for telling Subject A about my complains. not only Subject B told her about this but she team up with Subject A and argued with me. huh! i am feeling stressful now. what should i do? my mum told me that if i know this kind of person cant keep her mouth shut then dont talk to her anymore unless working topics. it is easy when my mum said that but it ia hard for me. cause i have to face her every 8 hours per day! 5 times per week! it is very hard to face her with silence! did u ever face such problem before? and how it ends? plus my friend told me to be ok with Subject A cause she is just all mouth and talking and talk less with Subject B cause she almost causes me a huge trouble.
