Worsen in Office

Situation worsen recently in my working office. The 3 fellows nv talk to me even since they knew i ordered pizza for lunch without them knowing.. They are like so so childish - 1 is a mother of 3, another 1 is mother of 2 and next is the worst, single and avaliable and is already past 30 years old.
I had a feeling of not coming to work everyday. I am sick n tired of such a working enviroment. So few ppl yet complicating.
Isn't due to different races or watever reasons? For your info, I and my AM is the only Chinese in the office. I really think I should change my job scope, working environment and most importantly my work place. I do not want to stay in a working enviroment where I m the only person working and the others are listening to music, watching youtube, etc. This kind of working style is really demoralising for me. Me too, dun feel like working at all. If this is the case, i would rather stay at home to do some cleaning up for my room, watch tv, surf net as long as i want, etc.
Therefore, no matter wat increment, how high is my BP, i m getting promotion next year, I make sure i leave latest by Feb 2009. I wil be sending my resume in December as i m completing my Dip soon. I m not going to care of whoever going to stop me from changing the job. I m sick and tired here. So much of anger to handle, rather than learning, yet so little pay. Tireddd.........
The most grateful ppl who is helping me this year is my AM and principal.. That is all..
I just want to leave this working place with no regrets and full of happiness...
